Best Buy has no stated policy about returning items without a receipt. In my online research, I found that individual stores will accept returns without a receipt if the items are unused, like-new, include all the original packaging and instructions, and has the original price tag. You will probably only get in-store credit or exchange.
At bed bath and beyond where I have shopped for 20 years and spent thousands I was told by a manager who has worked there 2 years maybe that I had too many returns and too many returns with no receipt. He insulted me in front of the sales associate and other people standing there. He said I can't just buy things and then return them when there's nothing wrong with them and I don't want them. I pointed out that most of the things I had returned had something wrong. And I did have a receipt. He just kept repeating himself at which point I told him to please stop repeating yourself I'm going to make a complaint about you. My return was processed and the sales associate was very rude to me after that. I called bed and bath one 800-number customer service she apologized for me being treated way that badly asked for the name of the manager and said his boss will be talking to him about treating me this way. I feel like I don't want to shop there anymore and that was one of my favorite stores now I'm going to have to drive to the other bed and baths in my area which are much farther away overall I will not shop there is much unless the higher up company management does something to apologize to me for this terrible treatment of a long time customer.
Unwashed, unworn or defective merchandise may be returned with a valid photo ID. Merchandise returned without a receipt will be refunded at the last activity/ sale price or the current selling price, whichever is lower, in the form of a merchandise credit usable on future H&M Store purchases.
