This argument never really holds water with me, why stop at card costs? Why not add on an additional fee for every other thing like, fuel surcharge on delivery costs, employee surcharges (I don't live in a place where tipping is expected), or even energy surcharges?
The cost of the product should be what's on the label. If that's not enough, raise the price.
