Pronounced "ay-feez"; acronym for Army and Air Force Exchange Service. A military department store similar to Wal-Mart, Target, JC Penney, or the like. Merchandise varies from store to store, and many offer name-brand items lower than the general retail price. (E.g., Coach purses) AAFES also imposes no sales tax. This is to provide a benefit to service members and their families, many of whom are often underpaid when compared to their civilian counterparts.
"AAFES' mission is to provide quality merchandise and services at uniformly low prices."
