Tbh I don’t vacuum seal soups, toss it in a glasslock and freeze. Year later it’s still fine because soup.

I live in an apartment, have a good commercial sealer, but it sits in my office, and just my fridge and a 7cuft (upright being key) freezer that’s in a closet. It’s more then enough space then I need to buy bulk from Costco, have a wide selection, and space for portions. 15 cu ft seems like way more then you need to just buy bulk and freeze?
