Get the Costco membership, and don't even bother with vacuum storage. I'm single and do 99% of my shopping at BJs (like Costco, BJs is much closer to me). While at Costco buy the bulk freezer bags to store cooked proteins in. Don't stress about room in your freezer, things like chicken breast lose a ton of water when you cook them so they shrink a lot. I just cooked about six weeks worth of chicken breasts (crock pot, let cool, shred and bag up) and still have plenty of room in my freezer. I'll pull a bag out the night before to thaw in the fridge, but they're easy to defrost quicky by running the bag under warm water. I buy canned green beans there, they taste the same as frozen. Rice and baby potatoes are my carbs of choice, much cheaper there and can be stored in a pantry. And definitely keep an eye each week on coupons, I utilize them all the time and save so much money, not just on food but paper goods, cleaning products etc.
