Couponing

I use to do pretty well cutting out coupons, going to the grocery store and then buying things that were on sale that I had a coupon for.

These days that just is not cutting it. I don't know if it's because I have many hungry mouths I have to feed, food prices have gone up or maybe my store isn't putting items for sale that may have a matching coupon.

I go to couponing websites and all of the abbreviations make it look as though they are speaking japanese. Sometimes the couponing scenarios take 2 coupons for one item to get the deals you see on Extreme Couponing. Well too many times I have tried that and have had a cashier treat me like I am trying to rob the store, so I just don't do it.

Are there any easy to use Couponing sites that don't speak a different language and are very good about using coupons in a legal way?

That is the question  :)
