I shop at Walmart (for hba, and pet supplies)
Save a lot for canned goods and snack type foods (just a few of those for school lunches) some baking needs
Sams - I buy all my meat, laundry soap, pastas, flour, yeast stuff like that......

I make almost everything from scratch - with the exception of Prego. I just can't make a spaghetti sauce I like and we love prego sooooo we still buy that. I make all of our bread.

If I could give up pepsi and chocolate - we would probably save another $40 to $50 but I love both!! LOL

I always make a menu out for 14 days at a time - I don't dictate what we have daily as I may not feel like making it that particular day. KWIM?
Dinners are normally 14 different dinners, Lunches are leftovers, sandwiches, fruit, salads
Breakfasts - eggs, cereal, oatmeal, homemade breads, cinnamon rolls, etc

Shop only with a list and give yourself $10 to stock up with - like if peanut butter is on sale for 99 cents I may buy 10 of them for the pantry. If I don't find a good sale on anything I set the stock up money aside- until a good deal is found.

I shop only with cash and a calculator.

I shop in my pantry/freezer first - seeing what I have that can be used with the dinner I have choosen to make.

There are a few things I don't make that would probably make my bill go down further - I don't make tortillas, homemade laundry soap (I just don't like - I buy l.s. at sams and I only use 1/8 of a cup in my front loader so a huge container lasts a long time), yogurt (but will be trying to in the next few weeks. )
