I think the answer is simple. The people who don't use vacuum sealers haven't tried them and don't know the difference. I have kept frozen game meat wrapped in plain wrap on a tray similar to what you get when you get a steak in the meat market. It was done that way in NewFoundland when I went caribou hunting. That lasted about 6 months before the meat started to show signs of freezer burn. The 2 following years I went again and put the packages in freezer bags which made them go about a year. I had always done my own deer for years and used freezer bags or butcher paper or both. I tried out a vacuum sealer and it was about three times as effective than everything else I had used. It would be a bit scary to break down the cost per pound of my game meat. Add in all the costs for equipment, trips, and vehicle costs and paying a bit more for vacuum sealed meat is a small price to pay.
