The use of this form is described in more detail in our book, Cut Your Grocery Bill in Half with America's Cheapest Family.
We used this form when we were first learning our prices (we got the idea from Amy Dacyczyn's Tightwad Gazette newsletter and modified it for us). It's a great tool to track prices between stores and price increases over time. Use one page for each item you want to track. You can fill in prices from the grocery ads or as you walk the aisles of the store. When you see a low price you'll know it's time to stock up and save!
After you've tried the form, leave a comment here and tell us if it helped you save any money.
