I got a ton of gift cards for my birthday recently, many for places I really don't care for, so I shopped around to see what I could get for them. I somehow stumbled upon giftcardchaos.com. At first it seemed too good to be true with promises of instant payment and no need for credit card info. I tried them out with a $10 card I didn't really care about that they offered $8.50 for. After giving them my paypal info, they sent me the $8.50 20 minutes later! After that, I went all out. Gave them 6 cards in one transaction and ended up getting $275 for $300 worth of cards!
I even signed up to this site to spread the info on them!
