We do the same too with meat. We like the Costco ground beef, good quality, and their stew meat. We seal them up in smaller packages. Diana from Wisconsin gave me a tip about vac sealing fresh fish. I love whole rainbow trout on the grill but the Costco packages just had too many. Now I vac seal one in a bag. In the winter I’ve been splitting them in half and putting them under the broiler. A couple of years ago I found a set of 3 foodsaver storage canisters on discount. A great find. Have my flour in one of them because I just don’t go through much flour. Just took out some broccoli from our garden which was just so sweet last summer, steamed for 2 minutes, let cool and vac seal. Tastes just as good as fresh picked. Nicest surprise was vac sealing fresh herbs from the garden. I had an abundance of oregano last year. It comes out wet when it thaws but the smell when you open the bag - amazing. Works great with chopped green onions, I do smaller bags to toss in soup or a rice dish. Not vac seal related - a great way to save fresh basil is to chiffonade it, stuff in a Ziploc, add olive oil to coat, squish around and press flat so no air is in the bag. just freeze, tastes so fresh in a pasta dish or when you want fresh basil.
When the vacuum pump on your sealer fails, save the unit to just seal. The new vac/sealers have overheat cutouts which slow up your process. Use the old unit to seal the first end to make your bag. Use the working vac/sealer to vac and seal.
