Bear in mind you're not meant to use the shop at all otherwise it would be completely unbalanced. Upgrades can be bought because there's no other way to get rails on weapons. I'm avoiding the repair cabinet so I have to use the oil cans I find and treating things that can't be repaired as disposable, but if I find there's one helmet on the entire map then I'll have to repair things like that with it.
