I had a question. Would you charge Processing tax?, like for example you are on a Mall and there are plenty of shop's called "Resellers" now you are one of them, you are the one that provides the best service on the block, not only support wise but that your merchandise has some nice features that others don't offer it.

Now the question is, on that mall the only one that charges processing fees is you. You got to pay the Anti-fraud gateway, CallCustomer, Billing System, Processing fees... Would you feel confortable paying a low tax of 2.5% Extra with that shop?
