Hi A.! Congrats on your decision to stay home! It's not easy but it's worthwhile!
I learned a ton from FlyLady.net - it's mostly about managing your home & finding peace there. But I learned a whole lot about menu planning. It makes your shopping trips more efficient - you spend a whole lot more when you're running out for this or that - you end up spending $20 when you just needed a gallon of milk. By planning and following your meal plans you save a TON.
I use an excel file with the things we always need then add whatever I think I'll make for meals then add all the ingredients I'll need. This allows you to also search your pantry & freezer for things you have on hand & plan how to USE them. :) I kept buying sour kraut over & over again, finally figured out I had a ton, so started planning meals I could serve with that (btw this stuff is great for keeping flu away!! When the bird flu went around there were reports that it stopped the flu! so chow down!). You get the idea. It helps a whole lot when you can use what you've already warehoused. :)
Good luck!

ps, I really recommend you check out FlyLady.net. She taught me so much about managing my home & time, has literally helped save my marriage because we had bad attitudes about things. It's more than just how to clean your home when it's trashed, though it helps a whole lot when that happens too! lol.
