Had a sweet experience trading in Putty Squad. Girl told me I was going to get $19.80 for it, which is double what I should have got. She had to scan it multiple times so it must have actually gone through twice.
I was going to just go with it, but then my conscience hit so I said "Wow, did the value increase or something?" and she said no, that because I was GCU I got double the trade in value plus the 10%. I knew this was wrong but I already kinda tried to point out her error once and I wasn't going to do it again. So I said "cool" and took the $19.80.
Thanks LaundryMatt, Putty Squad turned into a really good buy for me.
