Re: How to have customers pay the PayPal fee?
Unless you accept cash or check, you probably have to pay around 2% for all transactions through Paypal and CreditCard. Don't put that on your customers. And don't think it as a FEE, because it's NOT. While you have to pay them a certain (small) percent of the total, you get MORE customers. It's an INVESTMENT.
