Just an update on our search:
My husband and I are considering saving more and getting a freezer double the size we have now instead of upgrading just one size. We can afford the one size up now so I think we can save enough to get a larger one.
We were considering that we'd really like to store the beef, still get some Angel Food packages and also have room for other veggies, precooked foods, milk and bread. We would save a lot more by having the freezer room to stock up on the best deals and cook ahead to save time on meals.
