We buy meat in bulk, and after trying alunminum foil, freezer bags, wrapping in foil and putting in freezer bags, rubbermaid, etc. We figure what were saving in not buying all those bags and foil, that pays for the foodsaver bags, and now we dont have freezer burn and never need to throw stuff out. My pulled pork and brisket tastes just as good as the day it was smoked.
And if you havent tried it, try pouring some marinade in with chicken, steaks, etc, vac seal it, then freeze. Comes out great when cooked.
