Couponing on Limited Time

Okay so you find yourself with no extra time in a day, but you really want to or need to save money.  How can you do it?  In most Sunday papers there are only two different types of coupon inserts Red Plum and Smart Source.  At the end of the month or the very beginning of the next you add a third into the mix P & G.  From time to time there might be special inserts, but for the most part you will only get 3 types each month.
Here is what I suggest, if you look at any of the couponing sites that compile a list of  what's on sale that week you will see things like 3/14 RP or 4/1 PG these represent the coupon insert you will find the coupon in and the date of the insert.  Some coupons are regional so you might not have the coupon mentioned on couponmom, hip2save, etc.
Get three file folders, a pen and your coupon inserts.  Separate them into three categories (P &G, Red Plum, Smart Source), next in the three separate piles organize them by date, which you will find on the outside binding of the insert. I would suggest putting the oldest on top, but some people like to stack them newest to oldest.  If you have children ask them to help with this, it will help it get done quicker.   Label one file folder P & G, one Red Plum, and one Smart Source.  Stick the newly organized stacks into their respective folders.
Now, when you check out coupomom or sites like hers that tells you the item that is on sale, the percent you save, and the coupon it is paired with all you have to do is pull the folder and look for it.
Sounds easy, right???
After trying this for a bit, come back and let me know how this worked out for you.
