It's really hard to tell if somebody is legit when doing large auctions like these for their first sale. Maybe next time, try for a more simple auction until you are a trusted seller. You won't get as many credits the way you are going about this, and you also won't receive your credits until the winner has received the code. Not trying to be rude, I just wanted to give a bit of advice, as many of the more experienced listians are very wary of auctions like these. Best of luck! (If you are a serious listian, of course!!!)
