S.R.
I've been doing the Grocerygame since March. It has definately saved me money. You can get sucked into buying things that you don't need. The trick to it is stockpiling things that you know you will definatly need. For example I have 20 boxes of GM cereals in my "stockpile". Used my coupons and got the sales and I spent less than $2 per box. Laundy det, fabric softner, cleaners, FOOD! With a large family you know how much you can go through the snacks especially in the summer. I can tell you that I have cut my grocery bill in half. I have also earned rewards for fuel, FREE movie tickets and extra coupons.
There is just so much that I can say about it I don't have enough time to type it all. If you would like to send me a PM I would be more than happy to give you a call and/or meet you and show you exactly how its done. I live in the NRH/Keller area.
Check out the message boards on GG too. You see the good the bad and the ugly there! Check out one of my posts

Good luck and I look forward to hearing from you
