PayPal is just one example, there are lots of people offering electronic transfer. Rather than list them all I just picked paypal. Electronic fund transfers seem to be a good way to handle a quick, clean fund transfer. Nothing is perfect, even the US Mail will lose some of the payments. Look at the first Chip swap. Torn, lost & delayed packages. I'm STILL waiting on 2 chips from Shotgun II, I know they are in the postal system somewhere and wrote them off a while ago. I would hate for PAul to 'Write' off a few mis-directed payments. I'm not trying to sell Paypal.
