But don't buyers essentially pay the fees regardless of funding source, anyway? As a business, I'm sure you factor the cost of using PayPal into your prices and so forth, so when buyer does pay with PayPal, you still get the X amount of profit you want...so wouldn't that just make it more of a case that you want them to be more aware that they're paying those fees if they use an echeque?

Yes, but I don't know of any business that doesn't want to reduce their costs. Do you?
