michael t:Yard sales Lots of camping gear cheap
+1 you would be surprised what people practically give away at yard sales. (I got my coleman single burner stove for a buck... normally its around 40).
That being said, what sort of stuff are you looking for? (just curious).
When I tend to think of my survial equipment, camping gear isn't really on the list. I think of my Food supplies, generator, guns to keep the Zombies at bay. (I guess I do count my various stoves for cooking... that's camping gear I guess.)
