I sorted the pages into categories that I liked and used a black jiffy marker to write them on the page:
Cereals, Snacks, Meat, Dairy, Fresh Foods, Canned goods, Soups, Baby Pampers & Wipes, Baby Foods, Baby Toiletries, Cleaning...etc
This is what mine looks like:

There were more pages then I had categories for so I thought I would take it a step forward and put in pages for individual stores. When I sit down for the week and plan out our meals I make a grocery list at the same time using the sale flyers. Then I pull out the coupons I'll be using for that store and put it in their page so that when I go shopping there I have them at my fingertips. Here is a picture of them:

Then because I'm an organizing freak, I put in pages for my grocery list and to do list. This way I can set my photo book open on top of my purse and see my grocery list without having to keep track of a piece of paper. This way, it stays in place and you don't have to search for it!

For my last page I have a page for coupons to be used today. I put my coupons there if I need them for any store other then the ones I have specified. So another words, if I'm going to Safeway I will put my coupons for that store in the page for Safeway but if I'm going to Giant Tiger or say McDonalds and have a coupon I'll be using I put them in the last page.

My book is bursting at the seams so I started another photo album where I keep just my FPCs (Free Product Coupons)or higher value coupons.
So this my method of organization and it works well for me. Let me know how you keep yours organized.
