I love a good deal as much as the next person but when I can use my valid military ID card to get extra discounts on top of a good deal, I am a very happy camper. Take for example the super savings offered by retail stores at Tanger Outlets (visit TangerOutlet.com for locations).
I stopped by Customer Service at my local Tanger Outlet and discovered my military ID earned me a free coupon book (reg. $5). After thumbing through the coupons I headed to Under Armour to see what kind of sales they have right now and casually asked if they offer military discounts. To my surprise, the clerk told me they would accept the coupon from the book AND give me a 10% discount on top of the coupon savings! None of the other stores I went to would give me this "double deal" (including J.Crew, Nike, Polo, Banana Republic, etc) BUT most stores gave me a military discount of 10-15% with no minimum purchase.
BOTTOM LINE: Go to Customer Service and get your free coupon book. Remember to ask a sales clerk at each store if they will honor a military discount, and whether they will stack the discount in addition to any coupon savings.
