But there are many times when he's asked for upfront payment, and if he was going to scam he would obviously ask for upfront payment then and many would trust him enough or take the risk. I think if he was going to do this he would have done it already. People are just skeptical of others around here but it's not a bad thing really. 99.9% of people don't give shit away for free on here.
"I think if he was going to do this he would have done it already.". Indeed, but I don't think he ever will. There is no point in spending so much money in give aways just to build trust or something.
Like you said, in my situation BPB also sent a code before I did my part of the deal. There's no way to scam that way. Yes, codes might not be legit. However, I've got his Amazon code for many months now in my account and the balance has not been deducted. It's therefore legit.
