True-Coupons need to be used intelligently, and generally they encourage you to buy more expensive brands.
These books do help with that - you select the brand & product you already buy anyway, and it's already clipped - it should not take you an hour like it does clipping a few out of the Sunday Newspaper.
I'm looking into a method from a local mom here who pays almost nothing for her groceries, but gets bulk inserts from the paper. She cuts and sorts, uses local double/triple coupon days, and ends up donating her extra food to charity. With these books, she can get the same coupons without spending hours to clip...
But you do have an excellent point. Not everyone uses coupons-I should have said everyone buys groceries! (I have accordingly changed our advertising)
