An anti-trust suit from 2005 has finally been settled between merchants, credit card companies, and banks to allow retailers in 40 US states to add surcharges on credit card purchases. These fees are still illegal in California, New York, Texas, and seven other states. The fees are optional for retailers, and there will be no fee on debit card purchases, but if you often pull out the plastic, that 1% cash back might not be worth it much longer.
