Costco employees track return patterns and will flag accounts with frequent or questionable returns. Next time you bring something back, they might take a closer look to ensure everything checks out. However, if your return is legitimate, polite, and maybe even a little remorseful (like when your new sweater doesn’t fit), Costco will likely work with you.

​Costco’s return policy is incredibly generous, but don’t abuse it. If you repeatedly return big-ticket items, you might end up on their watch list. As long as your returns are reasonable and honest, Costco’s doors—and their famous $1.50 hotdog combo—will remain open to you!
