Sorry for my poor English I hope you understand what I was trying to say.
I think you should add little more warning like making people have to hit yes and then pop up a final warning like adding
If the code was not sended or not working or if the buying asking you to complete the transaction without you getting a working please report or something.
These 100$ cards for 40$ with ppl fake building up there rating by buying from a 2nd account is getting out of control.
I feel bad for ppl who rate the scammer because gameflip cant do anything after.
