Options. It's all about options. The more that exist, the better the odds are that a deal will be consummated at a price both parties consider fair. And no, raising my price on the contingency that someone "might" use PayPal to pay for it isn't just silly IMO . . . it's unfair. If a buyer doesn't want to use PayPal and a seller doesn't insist on it, neither should have to pay for it.
