Crystal @ Money Saving Mom has started a video series on 31 Weeks to a Better Grocery Budget! Crystal's blog was where I first got hooked on couponing, and there are some really good pointers in her series, even for the experienced couponer. If you are new to couponing and are serious about saving money with groceries, I highly recommend you check out Crystal's video lessons.
She is already on week 5, coming out with a new video every Monday, but I've posted her first video to get you going.
Check out her blog for the other videos in this series.
