Have you checked into USAA? I don't know how "discounted" they are, but they are strictly for vets and their families. We use them for our auto, property and life policies have always found them to save us alot of money. My extended family has used them for years through many car accidents, and even some natural disasters and they are awesome to work with during those times.
The only thing I am wondering is, my husband is not "retired"from the military or anything. He was just honorably discharged when his tour was up. Does that count??? Or do you have to be active or retired?
