You've got that right.
Other than weekly staples, like milk, eggs, bread, fruits and veggies, I do a freezer/pantry stock up about every 10-12 weeks....and then I will spend 2 days cooking and repackaging.....
It can never be said in this house "there's nothing to eat." If you walk away hungry after eating at my table, you have no one to blame but yourself :)
Yes, the freezer and pantry are the biggest moneysavers in the food budget universe!
If you have space to store stuff, you can really take advantage of sales. I never pay full price for meat. When it goes on a nice sale, I stock up and put it in the freezer. It's wonderful.
