I have used a paypal debit card before. Its not really very usefull unless you have income coming into your paypal frequently.
I, or course, will still use my credit cards. I will avoid places that charge fees if they are unreasonable. But I don't think any merchant is going to hurt their profitability by charging excessive fees.
What if the merchant charged fees without explicitly calling it a credit card surcharge? Such as, 'Buy this $100 item with cash/check/debit and get a $2 instant discount!" Would that bother you?
