PayPal Violations Per PayPals rules, specifically rule 4.5 it states:
4.5 No Surcharges. You agree that you will not impose a surcharge or any other fee for accepting PayPal as a payment method. You may charge a handling fee in connection with the sale of goods or services as long as the handling fee does not operate as a surcharge and is not higher than the handling fee you charge for non-PayPal transactions.
If it is determined that you are violating this policy by demanding a fee for using PayPal your thread will be immediately pulled without warning.
