hunting can be very cheap and cost efficient. buy a cheaper bow setup...hunt in homeade camos or military surplus BDUs or something cheap...hunt off the ground...etc etc.
really dont NEED much to hunt. really its ALL luxeries...think of the Native Americans. homeade longbows...homeade wooden arrows..homeade clothing...
i dont hunt for the meat. i EAt the meat..and love venision and wild game meat...but if i hunted for meat, id be a truely starvin college kid
i hunt because thats what i enjoy doing. if you dont see yourself enjoying it, i wouldnt get into it to "save money"
good luck with your decision though...
