So today I bought some JB Hi-Fi gift cards from someone. He could see I was wary about the gift cards as I was checking their balances one by one. So he proposed to show me the invoice from where he bought it from.
I thought great, so I can find out how much he paid them for. As he scrolled through his purchase invoice, I paid attention to any price I could spot, and it seems like he managed to get $100 gift cards for $41-$50, anyone has any ideas how he managed to get them so cheap? They were purchased from Auspost.
Scrolled through an electronic document that he volunteered to show you?
I wouldn't trust the legitimacy of such a document unless I had a copy for comparison.
