Our local one is Smith & Edwards (Motto: We have everything you want - if we can find it.) Used to have acres of belly tanks, odd tank parts, strange containers and such. Now, the surplus section inside the store has shrunken down to a few aisles, but there are still good finds in wool clothes, ammo cans, and insignia. Some mess kits, canteens, and fuel stoves with the occasional find. But really only a shadow of its former self.
Keep in mind that there have actually been wars since WW-II. All of them have generated surplus gear but rules of the goobermint have drastically limited what can be sold off to the public. Much of the "good stuff" has to be destroyed instead. Pity.
