ok so hypothetically speaking; "john" wanted some red sox tickets. he found a guy in boston on craigslist that wanted 250$ a ticket. these seamed like a great price compared to stubhub. he will not hold the tickets and will only accept paypal or money order. "john" is worried about paying 500$ for 2 tickets and having them never shipped to his house or finding out at the gate that they are fake tickets. "john" asked the guy to scan the tickets with a piece of paper that has his name on it so "john" knows there his physical tickets. the guy just sent "john" scaned images of the 2 tickets. so what can "john" do to make sure they are legit?
