ok another moral question...i bought something from amazon for like $30, 4 days ago. i sent it to the wrong place but didnt realize my mistake until it didnt show up in my mailbox. i then talked to a customer service rep asking for a refund or the item to be sent again. then like an hour after that call i realized my mistake and called back and told them my mistake and said i didnt need a replacement or refund anymore and apologized for the mix up. meanwhile i just drove to the friends house where i accidentally sent it and picked it up. now today i see that they refunded me anyway. so do i have any moral obligation to tell them im not owed this refund? i already told them not to give it to me once so im thinking im just going to take it and let it be but it does feel somewhat iffy.
