I am about to meet up with someone on craiglist to buy x3 500$ ebay gift cards for 1300$ cash. The Gift cards pin # has not been scratched off. So basically i check the gift card pin # if it is legit and then i use the gift card and buy something right away. Then i give him my $$$. Is there that could go wrong? - Not sh8t like getting robbed, but can my order be cancled or?
