When we stopped mid-week grocery runs, we began to save a lot of money. I plan a weekly menu anyway for my daycare, so then I have to pretty much stick to it...for me that forces me to keep with it. We do the majority of our shopping at Costco...it's once a week and that's it. Makes things easier and much better financially. I like it because it eliminates that "what am I going to cook tonight?" feeling and makes it easy once the weekly plan is done.
