This is my new coupon box. Charity and I got them at Staples (I think). They were about $10. This is the inside. I made my own labels.
In some of the categories I put envelopes to split it up into smaller sub categories.
I also have a folder where I keep my ads and an envelope for each store. When I'm figuring out my deals, I put my coupons in the appropriate store envelope. I still take my big coupon box in the store (in case I find any other deals or clearance items) but I have most of the coupons I need in the one envelope. I also do a list with all the stores and all the deals I want to check out. It lists the price, how much the coupon is for and what I should be paying for it at the end. I also list sizes that I have to buy in order to get the deal so I don't pick up the wrong size.
I don't have a method for getting rid of expired coupons. I usually just come across them in the store and then I fold them in half so I know not to use them. I have been thinking about going through them at the first of every month or every other month to weed them out.
It is work and it does take time. I don't have much money, but I do have time to save money. Right now it's my hobby and it's fun. I wouldn't do it (or maybe not to the same extent) if I didn't enjoy it.
