Yet, again like everyone else your eyes probably lit up with this guys offers. Even if he does 'pull through' ill bet you 50BTC his GCs are carded.
To the guy asking what 'carded' means, this means someone is fraudulently using somebody elses credit card, to purchase goods.
Do not assume because you have your GCs that 180days down the line amazon put your accounts in negative balance, and ask for the money back!
My most recent transaction with newdude was over 1.5 weeks ago, and the transaction before that was over 2.5 weeks ago. Total value was $2k+ in transactions. I'm not sure where you came up with the 180 day number for a supposedly stolen Amazon gift card code to reveal itself, but let's say that you're correct about the assumption of 30 to 60 days for a cardholder to discover and report unauthorized charges.
By my clock, 60 days is about 2 months. So by the end of May, if my Amazon account with its large gift card balance is still in good standing, and others can report that as well, I expect that you would owe newdude 50 btc, am I correct?
