Have you every tried to pay for something with a credit card only to find out that you were going to be charged a "small" fee to do so? Or maybe there was a minimum purchase requirement and you were forced to purchase something else only to "qualify" to use plastic? Well, I'm sorry to say you have been taken advantage of.
Terrica, of Fabuluxe Events in Georgia, has a great post today that goes into detail about the terms that merchants agree to when they allow credit card purchases. Be sure to read this information so that if you are ever confronted with this situation you can make a knowledgeable and sound argument.
