I would not bother to talk any further with the "buyer". What's the point?

Myself, I never deal with paypal anymore, PERIOD. I had a fellow paypal me money last night ANYWAY, in spite of telling him not to. He's going to have to retreive it, I'm not calling them.
I don't know why people would use paypal for any high ticket item, anyway. Get charged a nice percentage, what for? Go get a cashier's check or money order, and put it in the mail. Express Mail or Fedex if you are in that big of a hurry.
