I served in the U.S. military. I always get 10% discount (at least) from these businesses by showing my veteran ID card, which I got from the VA hospital. You may show your Active Duty/National Guard/Reserve/Retired IDs as well.You could save hundreds of dollars by taking advantage of these offers throughout the year. Some of these companies offer free services to military personnel. I spent a significant amount of time researching and verifying this information. These discounts work 100% of the times; "bring proof of military service."
