How do you organize your coupons?

Do you use a binder, a box, a coupon/check accordian file? I organize my coupons in a binder. It cost me about $15 to get the supplies to put it together from Wal Mart. I bought 2 packages of baseball card holders and a zipper binder. I had some white cardstock, a permenant marker and clear packaging tape at home so I didn't need to buy those. The great thing is that you can decide how many categories you want to organize your coupons in.

The categories I use are:

• Diapers/Wipes
• Baby
• Dairy
• Laundry
• Cleaning Supplies
• Paper Products
• Breakfast
• Condiments
• Snacks
• Juice/Drinks
• Refrigerated Meat
• Sides
• Frozen
• Health and Beauty (make up, oral hygine)
• Shampoo
• Body Wash
• Deodorant
• Shaving
• First Aid
• Feminine Care
• Pets
• Rite Aid Store Coupons
• Target Store Coupons
• Misc.

These categories are organized so that as I am walking through the sections of the store I can go straight to what I need and it somewhat matches the layout of the store I shop at most. There are so many ways to organzie coupons, so what way do you use?
