Books written by KrazyCouponLady and CouponMom are the two I highly recommend. Their techniques fit our family best, there is also a huge list in the back of CouponMom's book on how to cut your healthy food bill down. She goes into great detail how the MYTH that coupons are only for junk food and shares sites and links to get your bill down.

How to keep all those Coupons? There are so many techniques and each person opinion is different. I use a Couponizer and Binder system for my coupons(which really need a good cleaning after the holidays.) Coupon Clutch has some cute patterns to make your binder look like a tote. I will post photos of mine later on today. You just have to find which techique fits you. There is no wrong way, just different ways.
