If you go to the original thread of this signature I did state that I supported the project and did it for free, I'm not getting paid for this signature.
Just my personal opinion on this, either way why don't you just prove that you're really selling gift cards and not trying to pull a scam.
how you want to prove? by giving free cards?
No, why do you keep thinking that by giving free gift card proves that they're legit?
Well if you want me or any other member to give you any idea of how to prove, then you'll need to provide us details on how or where did you get the gift cards(which you keep avoiding to answer)
