Maybe my memory is faulty, but I never remembered having to pay a surcharge to use a credit card. Now everywhere I go there are signs saying that there is a 2.5-3.5% surcharge to use a car (and others that say that there’s a 2.5-3.5% discount for using cash, I assume to get around wording)
Buisness I work for will never take credit. The cheapest processing fees we’ve found are severeal percentage points more than our profit margin.
