Reducing My Grocery Expenses

I've had a revelation in the last couple of days. I spend way too much on groceries! For the last few years we have been on a pretty tight budget. So, my way of saving was shopping at Walmart and buying generic everything. Doing this I got us down to about $150 each week. This was good for us. Recently, however, I found out that I can be doing much better. I found www.moneysavingmom.com . The mom behind this site spends $35 a week on her family of 4. Seriously! I don't hope to get that good but if I could just cut my spending in 1/2 that would be a great accomplishment. So I have begun the process of educating myself on the system of coupons and store sales. Money Saving Mom has a handy little sidebar that helps you get started. She also breaks it down and makes it understandable. She makes it a game for herself to see how much she can save.
The wonderful thing is that we have something our parents never had. The internet. Where we can find out what the best sales and coupons are. Through Money Saving Mom I found www.pinchingyourpennies.com which has boards with savings listings pertaining to your state (some states are better than others, depending on how active members are from your state). I also found a page on that site that gave me sales according to my zip code and stores I shop at. From there I could even select items and print a shopping list out.
I'm still learning and hope to save lots!! If I achieve my goal that would be $300 a month, like a part time job!

I plan on getting some friends on this with me, I know there are several who could use the extra money. So who will join me?
