You could always form or join a local mom coupon group. When my wife has time, she plays with coupons. It's pretty much free money the way the stores have their coupons set up thses days and you can stock up on things.

Of course, there are some rather stange people out there in coupon world, but with the economy the way it is, this has become more popular.

Ideally, you avoid the competitive people who have taken to photographing their massive storge rooms full of 40 containers of detergent.
