I just saw your post about being a new mom. Congrats. My advice is sign up with every formula website. Sign up the grandparents and aunts too! You will not believe how many free samples and formula checks you will get. Sign up with Gerber, Beechnut, Playtex, and any other baby brand you can think of. They will start sending you coupons like crazy. Also sign up with Huggies (they over send coupons), Pampers, and Luvs. Not only will you get coupons for diapers, but wipes too. Johnson and Johnson is another good site. Check out Walmart.com and look under "in stores now" and then go to free samples. They always have diapers as free samples plus you will get coupons too. Both of my children were on Enfamil, and they sent me plus both grandmas $250 in samples and checks, plus a free diaper bag. Good luck with everything and enjoy it. It goes by so fast.
