Beginning Veterans’ Day — Nov. 11 — 18.5 million veterans who served honorably will be allowed to shop at military exchange stores and web sites. The Army and Air Force Exchange Service (AAFES) is finishing preparations for the influx of new customers. In the meantime, veterans can verify their eligibility online at ShopMyExchange.com. Once the program begins in November, they can shop online at that web site, or shopcgx,com, mymcx.com, and mynavyexchange.com.
