After I have entered my inserts in my spreadsheet I label a folder for that week, drop the inserts in the folder and file it away in my large box. When I have loose coupons, such as when I print coupons or receive them in the mail, I first make sure I enter them into my spreadsheet, then I file them in my small box.
My small box is arranged alphabetically by the product description field of the spreadsheet. All General Mills cereal coupons, for example, are filed under G since most sales are for "General Mills Cereals" and not for a specific cereal.
To find where a coupon is located I search my spreadsheet, locate the coupon I want and read the "code" column for that specific coupon. All the Insert coupons will have a code something like this: S 10/12-4. Which means that coupon can be found in the Smart Source insert for Oct. 12 (10/12) on page 4. Other insert codes are RP for Red Plum and P&G for Procter & Gamble.
Also in my large box I have a folder for each store I have ads or price lists for and a place for rebates. More on those and how I plan my deals in the next part of this series.
