I have to admit I enjoy watching TLC's Extreme Couponing. It's awesome to see these die-hard couponers saving money. While I love to save money, I'm never going to use coupons to stock up on soda and candy bars. I'll use them to cut my grocery bill (hopefully down by at least a 1/3) but not to buy things that I don't need or want. (No one needs 200 candy bars!)
So if you're just looking to cut the grocery bill down, check out this good article at Couponing 101.
