I've sold a product on Amazon before and had it warehoused and fulfilled by Amazon. Part of the problem with accepting returns is that you can't personally vet it for quality and correctness and when Amazon ships back out a returned item that the first buyer messed with, it would then have a high probability of getting returned again and/or result in negative feedback or a profit-destroying consumption of time trying to make the second buyer happy. It was then cheaper and easier to just have Amazon destroy all returned items, which is what I did. Part of me says that the person receiving a refund has no right to the item anymore and should return it on principle, but other side of me realizes it's just a waste of shipping and handling resources when I was having the item trashed anyways. As long as Amazon is actively trying to prevent fraud, I'm not really concerned about this policy.
