of course you have to sign up(follow instructions at http://www.shopmyexchange.com), and provide proof of being a vet. A DD 214 should do the trick..just scan and upload to the site. Shopping there is tax free, and if you spend 50 bucks or more , delivery is free. Does not allow you to shop in the exchange in person. That’s still reserved for active military.
I know that not everyone likes to shop online, but this can provide options when comparing prices. I’m signing up, for sure.
