Costco has been known to accept returns of almost any item, no receipt required. Although its "Risk-Free 100% Satisfaction Guarantee" offers refunds on most purchases and even membership, there are still some exceptions.

After 90 days, Costco will not take back electronics, including TVs, large appliances, computers, tablets, cellphones, smartwatches, and cameras. That's still a pretty good deal if you're trying to assess what size screen to get, or what sound system works best in your home.


Although some states allow returns of alcohol and tobacco products, in most places it's illegal for stores to accept returns of these items. Costco recommends checking with your local warehouse club before attempting to return wine, beer, or spirits.
