Your item is easily worth 10,000 to 20,000 credits. If you verify yourself and post good quality pictures of your card with your name on a piece paper next to it, you might as well get that amount. Otherwise you will end up with 3000 credits. If you want my bid, verify yourself (phone number, bank account) and post the pictures.
Wanna get your credit card or bank account verified? Just to see you are serious about listing your stuff here. I don't need my credits tied up for over 3 weeks through hassle and disputes if you never send anything. Not saying you are a scammer, but most new listians with no feedback will never send the code they are auctioning (when it's a digital code). There are exceptions though! Please become verified if possible. http://www.listia.com/account/verify
