SteveI was under the impression that 'outing the buyer'
would be his/her ebay name.  No one was asking for 
Name, address, phone number, email address etc.
Had the OP that day said, last week (ebay name) bought 
500.00 worth of cards from me and now wants to pay me in 8 weeks.
I'd have no problem with that.

Edit cuz I don't no ;-)the difference between 'know and now'
