Hell, if by some chance a seller were somewhere near by, I would pay in cash and meet in person in a public place of course.
Any other assurances a person would need to sell to me could be provided as well, as hard as it might be to believe, with as much scamming as goes on, on the internet, I am not trying to rip anyone off, or scam anyone, just wanted to get a good deal on some GPU's if possible.
