Boycott any business charging customers a fee for using a credit card! Customers shouldn't pay more if they pay by credit card. Spare me the 4% discount for paying cash, we're paying 4% more by using credit! The prices have always been the same for products or services through good and bad economic times regardless of whether we paid cash or by credit. Any business that isn't willing absorb the credit fee as a cost of business shouldn't be in business!
