TomfromPC, sitlet and Danediz, thanks very much for your advice. I'm pumped thinking that we might save literally thousands on this purchase.
Obviously, there must be some method that his organization has for him to make payment. I hope that my friend can pay with the exact cash amount and, therefore, no need for the organization to "make change". But if his organization is "not set up to accept /handle cash", as even some retailers are, is paying by debit card, or bank check, or any other method, preferable to using a credit card in maintaining buyer anonymity? (For example, isn't the only information on a debit purchase the user's account number, without a name?)
