Thank you.
We are basically the same two adults and my one year old and my two teenage step kids when they bother to show up.
I do not spend nearly as much as you on groceries.. With the daycare kids ( 2) I average about $ 600 a month including cleaning and personal hygiene.
I buy on sale and batch cook and LOVE my crockpot which helps keep costs down.
I like the idea of keeping restaurant receipts. We have breakfast out every Sunday and usually something takeout dinner once every two weeks or so.
