I see 100 dollar gift cards sell for 140 - 150, etc...why? I understand some people try to scam, but all you have to do is send the card with tracking, and they can't cashback. Do you think some of these people are legit and just too lazy to go to walmart? And about the "unauthorized payment" can't they do that on anything they buy? they can go on a scamming spree and get thousands of dollars worth of stuff. So why do it only on cards?
