Charging extra for any payment method while offering other common ones is not a problem at all. You have to consider the trouble that a massive number of merchants have with paypal. The risk of dealing with something odd is financially relevant. The time spent on conflict resolution (between merchant and paypal that is) consumes time, which delays payments and has a cascading effect on other operations. This time costs money, which many add as a fee for people that want to use paypal. I don't know a single commercial seller that once offered or still offers paypal payments and doesn't have a horror story that resulted in serious financial and operational trouble for them. PP could introduce this if they had a good image. Right now it's considered by many to be the ... Oracle of payment processing.
