I agree with Rickmazda, If you would verify your account , I'd bid but, It seems to good to be real. People look @ their credits as money besides that you won't get the credits until, the winner get's the item . Get verified , It's painless.
log in to listia.com on a PC or through your mobile devices web browser( NOT THROUGH THE APP). once logged in, on the left side under account settings there is 'verify your account.'
I would bid, BUT there is no information here, don't know if this is a scam. If you verify your account, you will be getting ALOT more bids and people watching. Until you get verified I won't bid, I have been looking for GTA IV and saved alot of credits for it. I will keep checking in to see if you have been verified or not!! Good luck.
