Where Should You Sell It?

You've got the item. You've already done the hard part — spotted it on a shelf, identified it, pulled the eBay sold-price median in seconds, and walked out with margin in hand. Now the part that quietly decides whether you actually make money: where do you list it? The same item on the wrong platform costs you 30% of your margin or sits unsold for six months. Branded electronics belong on eBay. A retired-pattern Brighton crossbody belongs on Poshmark. A graded rookie card belongs on Whatnot. A West Elm dresser belongs on Facebook Marketplace. The eBay sold price is the pricing anchor — the most public, comp-rich data signal in resale. The platform you actually list on is a separate question.

This is the full reseller platform comparison — eBay, eBay Live, Whatnot, TikTok Shop, Mercari, Poshmark, Facebook Marketplace, Depop — by category, fees, sell-through speed, and audience fit.

The five variables that decide the channel

Before you pick a platform, run the item against five variables. The eBay sold price answers the first one. The other four come from the item and the platforms themselves.

1. Average sale price. A $15 t-shirt and a $1,500 watch don't belong on the same platform. Low-ticket items get crushed by fixed fees and shipping. High-ticket items get crushed by Mercari's audience expectations. Match the median to the platform whose typical basket sits in the same neighborhood.
2. Sell-through speed. Capital recycles. A $40 item that clears in 10 days beats a $40 item that clears in 90 — you can flip the dollar three more times in the same window. The eBay sold-listings count over 90 days is your best velocity proxy.
3. Fee structure. eBay takes 13-15% all-in. Mercari ~13%. Poshmark a flat $2.95 under $15 and 20% above. Whatnot ~11%. Facebook Marketplace zero on local pickup. The all-in fee on a $50 sale ranges from $0 to about $13. That's a real chunk of margin.
4. Audience fit. Buyers on each platform show up looking for different things. The Lululemon Align buyer on Poshmark is already looking for Lululemon. The Lululemon Align buyer on eBay is comparison-shopping across activewear. Same item, two buyer psychologies, two closing prices.
5. Listing effort. A styled Poshmark listing takes 15-20 minutes. A Whatnot live show moves dozens per hour after prep. A Facebook Marketplace listing takes three minutes. Your time has a dollar value — the platform that fits your throughput often beats the platform that fits the item by 5%.

The eBay sold price is the anchor across all of this. The listing destination is a separate call — and the rest of this guide walks the eight platforms in the order they matter for most reseller portfolios.

eBay — the default for branded, model-numbered, comp-rich items

eBay is the default channel for a reason. Deepest buyer pool, broadest category coverage, densest sold-comp data, most mature dispute system. For anything with a brand name, a model number, or a serial number, eBay is almost always either the right answer or the right anchor to compare other channels against.

Best for: branded electronics (Cuisinart, Sony, Bose, KitchenAid), established-market collectibles, parts and components, vintage tools, sports equipment, books with ISBNs, sealed media — anything where the buyer is searching by a specific model number.

Fees: 13.25% final value fee on most categories, plus $0.30 per order. Promoted listings add 2-15%. Plan on 13-15% all-in for most flips.

Sell-through: highly category-dependent. Branded electronics with model numbers move in 10-30 days. Vintage and collectibles sit 60-90 days. The 90-day sold count is the cleanest velocity signal anywhere in resale.

Where eBay loses: fashion (Poshmark and Depop close higher), bulky furniture (Facebook Marketplace wins on shipping), live-auction collectibles (Whatnot moves faster), viral novelty (TikTok Shop now eats this lane). It's also slower to list than Mercari on sub-$20 flips, where listing time eats the margin.

If you're new to resale, eBay is where you start. The sold-listings data is the single most useful pricing signal in the industry — which is why eBay's number is the anchor in every three-second scan regardless of where you ultimately list.

eBay Live — auction format, sneakers, cards, watches

eBay rolled out live-streaming auctions to compete directly with Whatnot, and it now hosts daily shows across sneakers, trading cards, watches, comics, sports memorabilia, and high-end collectibles. Real-time bidding with a host running the show, layered on top of eBay's existing buyer base.

Best for: categories that benefit from auction urgency. Sneakers (especially limited drops and grails), graded sports cards, Pokemon cards (graded and ungraded), watches in the $200-$5,000 range, vintage comics, sports memorabilia, and high-ticket collectibles where bidding wars break out.

Fees: standard eBay final value fee, ~13.25%. No separate eBay Live fee on top — a meaningful advantage over Whatnot's stacked structure once you account for eBay's buyer-protection coverage.

Audience advantage: eBay's existing watch lists, alerts, and search saves. A Patek alert hits a buyer regardless of whether the listing is fixed-price or a live stream. That's coverage Whatnot can't match yet, especially for niche search behaviors embedded in eBay's recommendation engine for years.

Listing effort: high. You're running a live show — phone or tablet, decent lighting, 60-90 minutes of real-time selling. Throughput is strong on deep lots: 30-80 cards an hour, 10-20 sneaker pairs. The prep work (sorting, pricing floors, lot grouping) is what most resellers underestimate.

Where eBay Live wins versus Whatnot: bigger and stickier buyer base, more mature dispute system, and unsold lots convert into fixed-price inventory automatically post-show. Whatnot still leads in pure sports-card volume, but eBay Live is closing the gap fast on sneakers and watches.

Whatnot — live-auction collectibles, cards, sneakers, vintage toys

Whatnot is a core reseller platform, not a side channel. If you flip trading cards, sneakers, vintage toys, comics, Pokemon, sports memorabilia, or any collectibles category with an active live-stream community, Whatnot is often the first place to list, not the backup. Items that sit on eBay for 60 days clear in an hour during a hot live show.

Best for: trading cards (sports, Pokemon, MTG, Yu-Gi-Oh), sneakers, vintage toys (Hot Wheels, Funko Pops, vintage Hasbro), comics (raw and graded), sports memorabilia, anime collectibles, designer streetwear — anywhere a live community is sitting in chat waiting for the next lot.

Fees: 8% final value fee plus payment processing (~2.9% + $0.30), landing around 11% all-in. Plus shipping. On a $50 lot that's about $5.80 in fees, meaningfully cheaper than eBay's 13-15%. The advantage is biggest on sub-$200 items.

Velocity: the killer feature. A well-run card show clears 40-60 lots an hour with live bidding driving prices above eBay's fixed-price median on the same cards. Auction urgency creates pressure a static listing can't. Velocity per hour of work is the highest of any platform here.

Audience fit: Whatnot buyers are there to spend money in real time. They're not comparison-shopping — they're sitting in the live show with a credit card in hand. That's a different buyer psychology from eBay's watchlist behavior, and it's why hot drops often run higher than the eBay median would predict.

Where Whatnot loses: non-live categories. Listing a single Cuisinart food processor on Whatnot would be absurd. Items without live-bidding appeal (bulky goods, single high-ticket items, most fashion) belong elsewhere. And if you don't want to be on camera, this isn't your channel.

TikTok Shop — viral categories, beauty, accessories, novelty

TikTok Shop is the newest meaningful channel for resellers, and the dynamics are completely different from every other platform here. The buyer doesn't search for the item — the algorithm surfaces it, and impulse purchase happens in 30 seconds without leaving the app. It's a discovery channel, not a search channel, and the winning categories are entirely different.

Best for: beauty (viral K-beauty, indie skincare, niche fragrance), accessories, novelty, currently-trending toys (fidget, plush, character merch), Y2K fashion accessories, kitchen gadgets with a "did you see this?" demo angle. The test: if you can shoot a 15-second demo video where the item explains itself, it might be a TikTok Shop item.

Fees: 6-8% for most categories during the platform's growth phase, plus payment processing. Among the lowest fee structures here, though expected to climb as the buyer base matures. While the rates hold, all-in margin on TikTok Shop is genuinely better than any other channel for items that fit the algorithm.

Audience and discovery: impulse-driven, video-driven, predominantly Gen-Z and younger millennials. Buyers convert from organic videos and live streams, not search. Fundamentally different funnel — you're not optimizing a listing, you're producing short-form video that has to perform on its own merits.

Listing effort: high, but unusual. The listing itself is fast; the video content production is the work, and it has to be consistent. Resellers who treat TikTok Shop like eBay (post and forget) get zero traffic. Resellers who treat it like a content channel often outperform everything else on this list per item.

Where TikTok Shop loses: anything that can't be demoed in 15 seconds. Branded electronics with serial numbers, parts, antiques, anything where the buyer needs to verify condition — these don't fit the impulse model. Dispute resolution is also still maturing, so returns and chargebacks carry more risk than on eBay.

Mercari — clothing, kids' items, low-ticket where eBay fees eat margin

Mercari is the platform for items eBay's fee structure quietly punishes — the $15-$40 range where 13-15% take plus shipping leaves nothing on the bone. The audience overlaps with eBay's casual-buyer segment but with lower price expectations and a much simpler listing experience.

Best for: kids' clothing, casual adult clothing (non-fashion-forward), small electronics under $50, books, games, non-collectible toys, kitchenware under $40 — anything where the listing time on eBay would exceed 10% of the sale value.

Fees: 10% selling fee plus 2.9% + $0.50 payment processing, ~13% all-in. Comparable to eBay, but the listing effort is meaningfully lower — and that's where the real economics shift. A $25 Mercari sale that took three minutes to list is a better hourly rate than the same $25 sale on eBay that took 10.

Listing speed: the fastest here. Photos, category, price, ship with the prepaid label. Three minutes per item. For high-volume low-ticket flippers, that's the entire value proposition.

Sell-through: mixed. Fashion and kids' items move within 30 days. General household and small electronics often sit 60-90. The Promote feature (a small price-drop alert) helps, but expect slower clears than eBay on identical items.

Where Mercari loses: high-ticket items. The buyer base is price-conscious and lacks eBay's deep watch-list behavior for serious collectibles. Anything above ~$100 generally clears faster and higher on eBay or a category-specific platform.

Poshmark — women's fashion, designer, social-driven

Poshmark is the dedicated platform for women's fashion, shoes, designer accessories, and increasingly home goods. The model is social — sellers host parties, share listings, follow each other — and the buyer psychology is "I came here to shop for fashion" rather than "I'm comparison-shopping the internet." Closing prices on apparel reflect that.

Best for: women's clothing (especially activewear, denim, contemporary brands), shoes, handbags (entry-luxury and contemporary), modern jewelry (Brighton, Kendra Scott, Pandora), boutique and indie brands, increasingly some menswear and home goods.

Fees: flat $2.95 on sales under $15, 20% on sales above. The 20% take is the highest here, but it includes shipping and payment processing — so on a $50 sale, your $40 net is real, no further deductions. The structure quietly favors higher-priced items where the flat percentage feels less punitive.

Audience advantage: the buyer base is there specifically for fashion. A Lululemon Align that sits on eBay at $30 median often clears on Poshmark at $52 because the buyer pool is brand-aware, condition-aware, and not bargain-hunting across every category on Earth. For apparel the platform premium is real and measurable — see our Poshmark sold price guide for the categories where the gap is largest.

Listing effort: moderate to high. Poshmark rewards styled photography, multiple angles, branded cover photos, and active engagement. A polished listing takes 10-15 minutes. The algorithm meaningfully favors sellers who show up consistently — passive listings underperform compared to eBay.

Where Poshmark loses: anything that isn't fashion or fashion-adjacent. Don't list a CD player on Poshmark. The bundling and "offers to likers" structure also creates negotiation pressure that compresses prices below median if you aren't managing offers actively. Set your listing price 15-20% above your target net.

Facebook Marketplace — local pickup, furniture, appliances, no shipping

Facebook Marketplace is the right answer for bulky local-pickup items, period. Furniture, appliances, exercise equipment, large tools — anything where shipping costs more than the item or simply can't ship. Local pickup fees are zero. No platform take, no payment processing, just cash in the driveway. For the right categories that structure is unbeatable.

Best for: furniture (dressers, dining tables, sofas, mid-century modern, West Elm and CB2), appliances, exercise equipment, lawn and garden tools, large kitchenware, vintage finds too fragile or heavy to ship, baby gear, anything over 30 pounds where shipping economics would crush the margin.

Fees on local pickup: none. Buyer pays cash or direct payment. The single biggest fee advantage of any platform here, though it only applies to local. Opt into shipping via Facebook checkout and fees show up (currently 5% or a $0.40 minimum).

Audience fit: hyperlocal, bargain-hunting, lower-trust by default. Buyers expect to negotiate, expect to see the item in person, expect the price to be lower than retail. Fine for the categories above — the shipping savings more than offset the friction. Not fine for items that would clear higher with a national audience.

Listing effort: low. One or two photos, a short description, a fair price. About three minutes. The follow-up — messages, pickups, negotiation — eats more time than the listing itself, especially in active markets.

Where Facebook Marketplace loses: small, shippable, branded items where eBay clears faster and higher. Anything under 10 pounds and over $50 generally belongs elsewhere. The no-show rate is real too — plan on 30-40% of inquiries ghosting before pickup, and price accordingly.

Depop — Y2K, vintage fashion, streetwear, Gen-Z

Depop is the Gen-Z fashion platform — Y2K, vintage, indie, streetwear, anything with strong visual aesthetic. The buyer base skews younger and the expectations are completely different from Poshmark. Where Poshmark rewards brand-name contemporary fashion, Depop rewards curation, aesthetic, and rarity.

Best for: Y2K (early 2000s anything — low-rise jeans, baby tees, butterfly motifs), 80s and 90s vintage, streetwear (Supreme, BAPE, vintage Champion), thrifted and upcycled, indie and boutique brands, vintage band tees, vintage workwear — apparel where "vibe" matters more than brand name.

Fees: 10% selling fee plus payment processing (2.9% + $0.30), ~13% all-in. Comparable to Mercari and eBay, lower than Poshmark's 20% above $15.

Audience fit: the youngest buyer base here, with strong aesthetic preferences and trend awareness. On-trend items (Y2K currently hot, 2010s indie rising) clear quickly. Off-trend items, even objectively well-made ones, sit for a long time. This is the platform where fashion expertise matters most.

Listing effort: high. Depop is the most curated platform here. Successful sellers run cohesive shop aesthetics — consistent photography, consistent backgrounds, consistent tone. Random one-off listings get buried. Plan on building a shop, not just listing items.

Where Depop loses: anything outside Gen-Z fashion. A West Elm dresser doesn't belong here. A Cuisinart blender doesn't belong here. Even contemporary mall-brand fashion (Banana Republic, J. Crew) underperforms versus Poshmark. Depop is narrow on purpose — when an item fits, it fits hard; when it doesn't, it doesn't sell at all.

Scan once, sell anywhere — the workflow that ties it together

The reason all of this matters in practice: you don't decide where to sell after you've sourced the item. You decide before. The buy decision and the channel decision are the same decision — what's the highest-margin path from this shelf to a sold listing? The eBay sold price tells you the price floor. The platform mapping above tells you which channel to list on.

The manual workflow is brutal: identify with Google Lens, switch over to pull eBay sold comps, then mentally cross-check that comp against what you know about Poshmark for fashion or Whatnot for collectibles. Most resellers skip the cross-check because it's two more apps and another five minutes per item. The result: items listed on the wrong platform, sold for less than they should have, or sitting unsold for six months.

MarketplaceIQ collapses that workflow into a single tap. Snap the item and three things happen at once: triple-verified identification (so the search query is right), real eBay sold-listings data fetched in seconds, and a platform tip that names the best channel for this specific item. The eBay number is the anchor. The platform tip is the differentiator.

What lands on screen on a clean scan:

• eBay sold median, average, high, low for 90 and 180 days, plus sales count for velocity.
• Platform tip naming the best channel — eBay for branded electronics, Poshmark for women's fashion, Whatnot for cards and sneakers, Facebook Marketplace for bulky local pickup.
• Condition read where condition meaningfully changes the price (NWT vs used apparel, sealed vs opened, working vs parts-only).
• Reseller tip — what experienced resellers in this category watch for, from authentication red flags on luxury bags to date-code lookups on Coach.

The eBay sold price is your pricing anchor. The channel you list on is what actually determines your realized margin. Get both right at the moment of purchase and the rest of the flip is easy. Get one wrong and the rest of the flip is uphill.

Real-world examples — same source, different channels

Three items from one Saturday thrift run, three platforms:

Same source. Same scan. Three channels. The eBay sold price was the anchor in every case — but the realized margin depended entirely on listing where the buyer actually was. The reseller who lists every item on the same channel is leaving money on the table on at least two of the three.

This is what data-driven reselling actually looks like. Not a spreadsheet at the end of the month — a buy-and-channel decision in three seconds, at the moment of purchase, while you're still standing at the rack.
