Free: Contests & Raffles.
The other thing I would add is having a good tape dispenser is a life saver. Freezer tape is white paper with glue on one side. As it's dispensed it runs over a wet brush activating the glue. Works like a charm and very fast.
I put all my grind meat into vacuum bags then push the meat out evenly across the bag. They stack easy in the freezer and thaw quicker. Steaks and roasts I wrap in freezer paper.
I do a combo of both. All the ground up stuff, roasts and stew meat is done with paper and the prime steaks are all vacuum sealed.
