Incidentally, my own Best Buy story goes like this:
Around February of last year I received a birthday present from my sister. She got me 2 DVDs. A nice gesture, but they were DVDs I did not want. Rather than let her know that, I thought I would return the DVDs and let her continue to think she got me a gift I enjoyed. My sister buys ALL her electronics at Best Buy. I know that's where she got these (Although the partially torn stickers with the prices removed were a pretty good indicator as well), so I took the DVDs to Best Buy unopened. I was NOT seeking a refund. I wanted a merchandise exchange and would have been ecstatic with whatever the lowest store price was.
After waiting in line for quite a while, the 18 y/o kid working told me it was new stor policy to accept NO exchanges without a receipt. After clarifying that I didn't want money, I wanted a merchandise exchange, I asked to see the manager. He confirmed their new policy was to accept no returns without receipt. I told him I had never heard of a store adopting a policy like that, I thought it was ridiculous, and I couldn't believe a store like Best Buy would do such a thing. I proceeded to ask what they intended to do next Christmas - that they were going to have a nightmare on their hands. His response? "We intend to issue gift receipts with all purchases."
What the hell good is that going to do people in my situation? After that I basically got a #### you from the manager, was told if I didn't like it I could feel free to shop elsewhere, and I left the store with my DVDs in hand.
I ripped off the remainder of the stickers on each item, drove across the street to Target, and exchanged them with no problem whatsoever. The irony in this is that they easily could have re-sold the 2 DVDs I was returning, probably at a greater price than they would have given me in return, while the item I wished to exchange for was a concert DVD that they probably sell about 1 of per year. I have not returned to THAT Best Buy store again, and I won't do so. As a consumer, what other recourse do we really have? Yes, I could waste more of my time #####ing to a manager at a higher level, but at the end of the day it simply isn't worth it to me. It does me no harm to shop elsewhere.
