To start gathering your price info you can check your recent receipts, check the sales paper for the regular prices or sometimes visit the store’s website. Harris Teeter has a feature called Fast Lane and while it’s designed to let you order groceries online and then stop to pick them up, couponers can use it to get the prices of items they’re thinking of buying.
Your price book page might look like this:
|Cereal||Store 1||Store 2||Store 3|
The price book is a work in progress. You’ll keep adding to it as you shop.
