of course not. That's absurd.

I want a single price, regardless of my choice of method of payment. The cost should be built-in to the price. If the cost of providing one type of payment method is too high, i want the business to take out out to make their price more competitive (balanced with the amount of people unwilling to shop there without said payment method).

Merchants and payment providers compete to provide payment methods at as competitive rates as possible, because they needs to compete with cash handling (which isn't hard at all), and the consumer doesn't think about "cost of payment method" - they merely need to think about the cost of the item displayed.
