Does anyone know a good source for the larger ammo boxes? I want to get 2 of the 81 mm boxes like this http://www.galleria-e.com/cgi-bin/Co...product/134201 . The problem is because they're so large the shipping would be nearly 50 bucks for the two of them. I was hoping to find a army surplus store somewhere local with them, but so far I haven't had any luck. The places in college station only had the smaller boxes, and the places I checked out here in houston (command post, etc) had no boxes at all
