TheKrazyCouponLady.com is an amazing site. She has pretty much every store available. She has a Let's Shop page that shows you how to shop like her. Sometimes she'll have $5 or less at certain stores to help you get the same deals she will be getting. After that sales week is up, she shows you what she got and how much she spent. It's like a tutorial to help get you started. There's even a Bragging Lounge to see other people's bargain hunting deals and how they accomplished it. This is one of the sites that helped me start out with couponing and get to where I am now with my stockpile.
MoneySavingMom.com is another one of those amazing sites you just can't stay off of. She has DIY projects, ways to save around the house, homeschool ideas, and even freezer cooking! I love this site because of the variety of subjects she blogs about and most are things I already do in my life.
