Can Merchants set a min. Purchase amount for Cards?
Bought a $1.15 bottle of water this morning at the gas station. Haji or whatever his name was, told me $2.00 minimum purchase amount for card transactions. I told him I work for Visa and we both know that's a violation of his merchant agreement. He sold me the water.
Am I right on this? I've heard so many conflicting reports, but is a merchant allowed to set a minimum purchase amount for cards?
