I found a man on a Craig's List posting that is selling NFL football tickets that I am interested in. He said that he has more offers so I would need to pay him today. If I pay through Pay Pal and once he received payment, he would then over night the tickets. Is this safe? What happens if this is a scam? Is there any way that I can protect the money if they are fake or how do I go about doing this safely? Thanks!
