Lady I know bought a coffee maker at Walmart as a Christmas gift for her neighbors. She was horrified to find that when the neighbors opened the cafefully sealed box there was an old, dirty, used coffee maker inside.
I bought a humidifier from Target once and when I got it home it had been used and abused since it had several cigarette burns on the top of it. It was so gross. I was more ticked that the store was an hour from my house and I now had to go return it.
That said I once bought a pair of jeans from a store and found out the zipper was broken so I returned them showing them where the zipper ripped. They didn't have another pair in my size that day but a couple weeks later they had a pair in my size. I looked at them and they were the same pair with the busted zipper. I took it to the manager and told her the issue. That pair of pants were back on the rack the next time I went in again. I think they were waiting for someone to just keep them and not return them.
