Our basic bi-weekly grocery list has looked about the same for 3 years.
3 years ago, it came to about $120. Currently, we pay a little more than double. And the items that push it up the most are bread, eggs, and some of the produce, in that order.
I can totally do without the bread. A loaf of Orowheat went from $2.80 to $5.50, they're smaller, and the bread tastes off lately. That's just an example.
I'm gonna tweak the whole list. I can make bread (believe that, or not). They're rolls, but that's fine, they do the same job. And I can make soups and stews; they're easy. Pasta and bean dishes are, too.
