I just buy things and don't sell them, even if they turn out not to work for me. Like I bought a battery for my old laptop and it didn't fit and I was too lazy to bother with posting it back and getting a refund. I also just bought some pedometer bands that are way too small because I forgot to change the size when I ordered them and ended up with petite size, and I probably won't return those either. I'm going to try to get up the oomph to return them though. The packaging is still pretty much fine and I didn't wear them obviously.

I often buy things, get home, and think, why the heck did I buy THIS?! and immediately regret getting it. But I'm not much of a seller.
