RE: bare necessities of deer hunting...
After gun, knife and ammo, I'd put a drag rope.
As far as clothes, which camo doesn't matter, you can get a lot of good deals on clearance stuff. Get some thing waterproof and depending on where you live, warm. Good water proof comfortable boots are key also.
A small pack to carry things, compact binos, and a grunt call, would be my additional BARE minimums.
