Costco is known for its 100% satisfaction guarantee on most merchandise. Although there are exceptions, Costco often refunds the full purchase price of returns. It may even be possible to return some items without a receipt or the original packaging. Costco exchanges are handled a bit differently than you may expect, though.
Due to the nature of their inventory system, Costco does not perform true exchanges. Even items that are the same brand and product may have different codes in the system, so simply swapping items over the counter could make inventory inaccurate. Costco exchanges are therefore considered a return followed by a repurchase. In order to avoid a delay in credit being refunded, it's best to exchange merchandise at a local Costco warehouse instead of shipping it back. Costco will not refund the amount owed until it has received and fully processed the return.
While merchandise purchased at a warehouse must be returned to a warehouse, online order returns can be initiated online. After signing in on the Costco website, take the following steps to begin the return and repurchase process:
Some items can't be returned and some items can't be returned through self-service. In general:
If the option to return your merchandise doesn't appear online, you'll have to contact Costco or visit a Costco warehouse for additional support. Costco's support team can also assist you in checking inventory during the repurchasing process.
