Skip the hardware store for these guys. Grocery store, in with the wax paper, aluminum foil and the like. Tell the clerk you are looking for a plastic oven bag, for moist cooking of chickens. If they look at you funny, tell them truth- the technique was developed by the french years ago.

While you are there, look at the aluminim foils. They should list thier length. Weigh them by hand, and take the one that feels heaviest compaired to the length of the roll.

And breast milk bags. Very good, best zip seals ever, and great water bags. And don't forget the value of feminine hygine producets in both first aid and firestarting.

Yeah, our addiction requires a certain lack of shame. :P
