A lot of new Amazon sellers researching “wholesale suppliers” start at Costco Business Center or Sam’s Club – membership is easy to get, and the shelves are already stocked with the same national brands that sell well on Amazon. It feels like the fastest way in. Amazon’s own seller community has been answering this exact question for years, and the answer is more consistent than most new sellers expect.
Why Club Stores Look Like a Shortcut
There’s no wholesale-account approval process to go through – just a membership fee. The shelves are already stocked with recognizable national brands, and Costco Business Center locations sell genuine case-pack quantities, not just single units. For someone new to sourcing, it can look like a real wholesale relationship without the usual vetting.
What Amazon’s Own Sellers Say About the Receipt Problem
When you apply to sell a gated brand or category, Amazon’s review team asks for a supplier invoice – not a purchase receipt (see our ungating invoice requirements checklist). Across multiple threads on Amazon’s own Seller Central forums, the consensus from other sellers – and from Amazon staff who’ve responded directly – is clear: a Costco or Sam’s Club receipt is not an acceptable substitute. As one Amazon representative put it in a forum thread, invoices “must come from the brand or an authorized distributor,” and because a club store is a retail outlet, its receipts “are not valid” for that purpose. Another thread put it more bluntly: “Costco is not a wholesaler despite its name.”
That said, the confusion is genuine and ongoing – new sellers keep asking the same question, and a few forum posters point to specific Kirkland Signature or club-exclusive items already selling on Amazon as evidence the rule might have exceptions. Multiple experienced sellers respond to those cases the same way: buying at retail breaks the supply chain a category-approval review is designed to verify, and “buying items from Costco and trying to sell them on Amazon is a quick route to suspension.” If you’re counting on a club-store receipt to get approved in a specific category, treat that as a real risk, not a shortcut.
The Quantity Problem
Even setting the invoice issue aside, club stores cap how many of a hot item you can buy per membership, per visit, or per online order – fine for personal use, a real limitation once an FBA listing needs consistent case-pack restocking. A distributor relationship is set up for repeat purchase orders at the quantities an active listing actually needs.
When a Club-Store Run Still Makes Sense
For a one-off test buy, or an occasional item in a category that isn’t gated, a Costco or Sam’s Club trip is genuinely low-risk. The risk is specific to using that same receipt later to try to unlock a gated brand or category – that’s the step where Amazon’s own sellers and staff say it consistently falls short.
What To Do Instead
If the goal is ungating in a real brand’s category, start with an invoice built for that purpose from day one – a dated invoice number, itemized SKUs and quantities, and your registered business details alongside a supplier whose authorization Amazon can verify (see our guide to verifying an authentic wholesale distributor) – rather than hoping a retail receipt gets approved after the fact.

Frequently Asked Questions
Can I use a Costco or Sam’s Club receipt to get ungated on Amazon?
Based on years of discussion in Amazon’s own seller forums – including responses from Amazon staff – the consistent answer is no. A club-store receipt is a retail purchase record, not the itemized business-to-business invoice Amazon’s category-approval review is designed to check.
Why does a wholesale distributor invoice work more reliably?
It’s built as a business-to-business document from the start – a dated invoice number, itemized SKUs and quantities, and your registered business details alongside a supplier Amazon’s reviewer can verify – rather than a retail purchase record from a store that isn’t an authorized distributor for the brand.
Can I still buy in bulk at Costco Business Center for resale?
Yes, case-pack quantities are genuinely available there, but per-item purchase caps still apply on popular items, and it remains a cash-and-carry retail purchase rather than a wholesale account relationship – fine for a non-gated test buy, risky as documentation for a category-approval application.
