It was reported that an agreement was reached between Department of Justice  (DOJ) and Visa and Mastercard on the fees that these companies charge merchants.  This is good news for customers and store owners because the DOJ estimated that the fees cost merchants $35 billion and that those costs were passed on to customers.  In addition the DOJ announced that they filed an antitrust suit against American Express.
