How to buy Costco return pallets
Costco sells its returns and overstock through Costco Liquidation Auctions, which runs on the B-Stock marketplace and ships from Costco depots nationwide. That’s Costco’s official liquidation channel, and the lots lean toward appliances, electronics, furniture, general merchandise, and outdoor gear, sold by auction and usually manifested.
To buy well: work from sources that publish a manifest and clear condition grades, value the lot on real resale comps rather than MSRP, and price freight and the buyer’s premium in before you bid — Costco lots ship heavier than most, so freight matters more here than on almost any other storefront. Below is the step-by-step, plus how to see what’s actually live right now instead of guessing.
Where Costco return pallets actually come from
When something is returned to a Costco warehouse or doesn’t sell through, it usually can’t go back on the floor as new. Costco routes that inventory into liquidation, and its official outlet is Costco Liquidation Auctions on B-Stock — pallets sold from Costco depots nationwide, usually with a manifest. We know of no other public Costco liquidation site as of the last review, so buying there is buying at the source: a “Costco pallet” advertised anywhere else has passed through at least one reseller first. The full review of the storefront — fees, categories, pros and cons — is at bstalker.com/directory/costco.
Plenty of lots advertised as “Costco returns” elsewhere are resold by middlemen, sometimes at a markup over what the original source charged, and social-media “pallet deals” are where most beginners overpay. The rule that protects you is simple: buy from the original liquidation marketplace, insist on a manifest and a stated condition grade, and be skeptical of any “Costco pallet” sold without either.
What’s live right now
BStalker watches B-Stock — where Costco Liquidation Auctions runs — alongside eight other US liquidation marketplaces, in one feed.
- 1,985 live B-Stock lots — the marketplace that hosts Costco Liquidation Auctions (note: B-Stock also hosts Amazon, Walmart, Target and 40+ other storefronts, so not every lot is Costco-sourced)
- 23,570 live lots total across 9 platforms, searchable by keyword and category
Closing soonest among live B-Stock lots matching “Costco” — by title, seller, or manifest contents. $/u = the lot's total cost divided by the unit count the source publishes.
Because BStalker indexes manifest contents where the marketplace publishes them, a search for a specific product matches items inside a pallet, not just the lot title — useful when you’re hunting a category rather than browsing. B-Stock coverage detail is at bstalker.com/platforms/b-stock.
How to buy, step by step
One, register on the marketplace — Costco Liquidation Auctions on B-Stock is a business-buyer channel, and a resale certificate is required to register. Two, find lots in your category and read the manifest and condition grade, not the headline “manifest value”. Three, value the lot from real resale comps and discount MSRP hard — check live retail prices on the same items to know your real spread, and expect some cosmetic damage from warehouse handling on returns.
Four, work out your true landed cost — cost per unit is (winning bid + the 10%buyer’s premium + freight) ÷ units — and be extra careful on freight: appliance and furniture pallets ship heavy, and the winning strategy on Costco lots is usually local resale within driving range of a depot. Five, bid, win, pay, and arrange freight or pickup. The full beginner walkthrough is at how to buy liquidation pallets, how to read the manifest is covered at how to read a liquidation manifest, and what lots typically cost per unit, live and by category, is at liquidation pallet costs explained.

FAQ
Where can I buy Costco liquidation pallets?
Costco Liquidation Auctions on B-Stock is Costco’s official liquidation channel — it sells returns and overstock from Costco depots nationwide, so a "Costco pallet" advertised anywhere else has passed through at least one reseller. Buy from the original source, insist on a manifest and clear condition grades, and avoid social-media resellers reselling pallets at a markup.
Does Costco sell liquidation pallets directly?
Costco’s returns and overstock are sold through Costco Liquidation Auctions on B-Stock, shipped from Costco depots — that’s Costco’s official liquidation channel and the closest thing to "buying from Costco." Pallets advertised as "Costco returns" elsewhere are resold through third parties, so check whether the seller is the original liquidation source or a middleman adding a markup.
How much do Costco return pallets cost?
Like any liquidation lot, the sticker ranges from under $100 for a small pallet to five figures for a truckload — but cost per unit is what compares them: (winning bid + buyer’s premium + freight) ÷ units. B-Stock’s buyer’s premium is 10% (per its own Supply FAQ), and weigh freight hard — Costco lots lean toward appliances and furniture, which ship heavy. Live median cost per unit by category is at bstalker.com/guides/liquidation-pallet-costs-explained.
Are Costco return pallets worth it?
It depends entirely on the manifest, the condition grade, and your sell-through — returns resell for a fraction of MSRP, and no one sells 100% of a pallet. Costco lots carry higher-value individual items than most sources, but they ship heavy, so freight can decide the whole lot — read the manifest, discount MSRP hard to real market comps, and price freight and premium in before bidding.
