Common Questions About Costco Wholesale Returns
The Full Picture: Costco Wholesale Returns
Costco has no time limit on returns for most items under its 100% satisfaction guarantee. Electronics and major appliances are the main exception at 90 days. TVs, computers, cameras, drones, tablets, cell phones, and major appliances all fall under that 90-day cap. The rest, including mattresses, furniture, food, clothing, jewelry, and tools, has no expiration date. People have returned mattresses after two years and gotten their money back.
You never need a receipt at Costco. Your entire purchase history is tied to your membership card, and every transaction since you joined is in the system. The returns counter can pull it up instantly from your card or membership number. This also means Costco tracks your return patterns, and accounts with excessive return activity may get flagged or have membership revoked. Most members never get close to that threshold, but it's good to be aware of.
Diamonds over 1 carat have a special procedure: you need to get a Costco GIA assessment before the return can be processed. This takes a few days, so don't wait until the last minute. The same diamonds that would be $8,000 at a jeweler often run $4,000 at Costco with the same or better certification, so returns do happen.
For electronics past 90 days, the Concierge Services line (1-866-861-0450) is worth knowing about. They handle tech support, manufacturer warranty facilitation, and can sometimes bridge the gap between a product failure and getting it resolved, even when a return is off the table. For appliances, the same logic applies: 90 days for returns, then manufacturer warranty, then Costco Concierge as a facilitator.
