On
ebay USA, the system automatically sends out an invoice to the buyer on completion of the auction. It will not be a combined invoice - this the seller has to do - but an invoice is automatically sent out. The whole invoicing system is messed up, because sometimes a buyer cannot manually combine purchases/payments and then you end up with separate PayPal payments, which cost the seller extra money in fees because of the
refunds, and etc.
When you say he had not set the postal locations properly, is it possible that he only accepted payment by PayPal? If so, he would not need postal location set up, because he would expect a contact mail (Is it okay to send a check or money order, and if so, what is your mailing address) before the sale...
I think that all of this comes down to communication and fair treatment on the part of both buyer and seller. I am sure some sellers are lacking in their skills, but, as an active seller, I also know that there are plenty of lousy buyers out there, too!
