I am retired Navy and am looking for any business or restaurant that offers a military discount. 10-25% just for asking and showing my ID Card. Not Bad!
Fort Jackson Commissary in Columbia is just a bit too far, but if I am down that way, I will stop. (Package Store)
Here are some places I found that do give service members a break.
Home Depot and Lowe's 10%
Foot Locker/Lady Foot Locker 20%
The Finish Line
New York and Company, my wife asked and got 20%
Autozone
Wilson's Leather
Quizno's
Bass Pro Shop
Bath and Body Works
Know of any others?
