Any payment processing advice?
noodle: 1) a safe policy would be to accept checks by mail, but hold shipping until the check clears the bank and you have funds in your account.2) http://www.gabrielweinberg.com/startupswiki/Ask_YC_Archive#t...3) depends.  some of the things in the link above touch on that.  for the most part, though, keep as much of the "safe" (non-CC, check, routing, etc. numbers) information that you feel like you need.
