Where can I get cheap, or free military MRE's?

I want to get more MRE's for camping, hunting, outdoors etc. However, I can't keep spending $65 a case on eBay. I heard online that if I knew someone in the military, they can get as many they want for free. But I do not know anyone in the service. Does anyone know where I can buy MRE's for cheaper than $40 a case or where I can meet someone in the military to get them? I live in NJ. Thanks a lot.
