Think prices at the exchange are too high? Think again. The Army and Air Force Exchange Service (AAFES) guarantees the best price. AAFES buyers work with vendors to get the best prices to pass on to service members and their families. Price surveyors check the local competition to ensure exchange prices are competitive. But in case they miss something exchange customers can use the Best Price Program (in U.S. exchanges only -- not overseas). The Best Price Program is simple. If a customer finds a product carried at the exchange that is offered at a lower price elsewhere, AAFES will adjust its price to meet the local competition. Customers need only bring in a current competitor's advertised price. If the difference is less than $5, AAFES will lower the price immediately, no ad or verification required. AAFES also offers a 30-day price guarantee. If a customer purchases an item from the exchange and finds it advertised at the PX or a local competitor at a lower price within 30 days, AAFES will refund the difference. The Best Price Program is one way AAFES meets its mission of providing soldiers and their families quality goods and services at the best possible prices. By shopping the PX military customers save money and support their military communities. It really does pay to shop the exchange first.
