we try to use as many coupons as possible. And it drives me nuts having a good coupon and not being able to use it..... because I don't drive we have to have a good system (and it works sometimes and sometimes not)........ here are my tips.......
1) if you have more than one coupon for something .... layer them and cut them out at the same time. .... if you are asking the kids to cut them, tell them to cut OUTSIDE the lines.
2) find a coupon holder or some kind of keeper that works for you.... I have not put together a binder but I know some people use them well. for now I just have the accordian style holder its probably as big or longer than a business size envelope.
catigorize: I have sections for:
FREE
STORE COUPONS
CEREAL & BREAKFAST
CANS
BOXES
SAUCES & MIXES (GRAVY ETC...)
BAKING
PAPER GOODS AND HOUSEHOLD (toilet paper, paper towels, cleaning supplies)
DAIRY & REFRIGHERATED (meat, biscuits, cheese)
FROZEN
PERSONAL (razors, shampoo, tums, etc..)
3) try to use a manufactures coupon with a store coupon or sale! (tricky at some stores) but once you know your store's policy it can work most of the time.
4) use your sales papers and make a list!.... make a symbol (I put the letter C inside of a circle for a coupon or an F inside a square if I have a free coupon) ... anyway it lets my husband know to look inside the coupon holder when he sees that symbol.
5) if you are stock piling, make sure you are shopping when there aren't going to be long lines, so you can get things strait and not make anyone mad at you.
6) send off your expired coupons to a military base (there are website instructions if you google it) or get rid of them...... so you don't see a coupon with high hopes only to get to the check out and find out its expired.

7) start slow..... you won't have a stock pile instantly, if you have room for stock piling, I don't so I just use coupons on our weekly items, we'll get a few items if we know its a rally good price....
8) find coupon friends, either at church, on line, or your neighbor...... let them know what kind of products you use most and they can set them aside for you when they see them and you can do the same thing...... I personally like seeing Kool-aid, crystal light, country time lemonaid type coupons, and Maxwell house.....
GOOD LUCK....... don't get frustrated. Use the blogs to your advantage there are so many of them!
