I have friend who does extreme couponing. All the time she puts into it is not worth it to me. But she turns around and donates a lot to the shelters and food banks. She also sells some of it to friends. A lot of the stuff is so heavily fragrant that you can't stand to go into her house. I must say she has had to move a lot of it to her garage. About the most I've ever saved is when they have double coupons which isn't very often. I saved about $10.00 on a $135.00 bill for groceries and it was for a holiday dinner. She does donate 80% like the canned goods and a lot of toiletries and toothpaste/brushes and deodorant.
