Extreme Couponing

So, I've always used coupons, at least casually, since I first moved out of my parents' house. I haven't always done as well as I should with them, though. Last year my husband was deployed for several months, and during that time we ended up accumulating some extra debt due to poor communication, overspending, etc. So one of our biggest goals this year is to use more coupons, and watch sales more closely. I've managed to keep our grocery budget under $300 a month for quite a while anyway (we're a family of 3 with two dogs), so now my new goal for the first half of the year is under $200. If I can attain that, I'm hoping to drop it to around $150 for the second half of the year, and leave it there.
