I don't think that the GP was necessarily complaining about the money, but about the inconvenience of the payment. > Having to provide an address and a credit card You don't usually complain about providing an address if the only factor is the payment/price. I suspect the GP would have been fine paying if they had an extremely low-friction payment system (e.g. one-click).
