Oprah just aired a pre-record show on savings, which is still very timely. They have a few good ideas, including the following:
1.) Understand supermarket store policies on buy 1 get 1 one free (some times you only need to buy of the item in order to realize the savings)
2.) Combine store savings with grocery coupons
3.) Get mulitple papers that contains the coupons you want
4.) Make a list of the things you NEEd vs. the things you WANT
5.) Get rid a land line and use your cell phone
6.) Don't spend more in a given month then you take in
7.) Keep a diary of your spending
