Yes, I know there are a ba-gillion coupon and savings blogs out there, but I have just recently found this one, and am quite fond. It is the Deal Seeking Mom blog.
This blog has tons of stuff, from indexes of coupons (here) to even matching up coupons you can print from them to the weekly adds of local grocery stores (here). There is even a section/link to free samples you can order from various companies. Can you say awesome?
Not only that, but this site has coupons ranging from Victoria Secret to Go-Gurt. Now, what mom doesn't need a little of both those things ;)
