If you sign up for email from Foodsaver you will get great discount sales on bags and other items every few months. The last sale I got the freezer bag roll of a variety of sizes for 50% off. I stocked up until the next sale. I double seal both ends of the freezer bag items. I've never had one lose vacuum with the double seals. I keep it out on the countertop and we use it to reseal most all packages.
