"Deals for mommy" is pretty nice. They email great deals for both pregnancy and baby. I've bought quite a few things through them..

Huggies or pampers also babies r us has coupon books and you can go on eBay people sale coupons for diapers and wipes
Girllllll most of that stuff is just a scam. And they send you spam mail and sale your email and stuff to other companies so they can bug you with stuff too. Lol there are some legit ones, but its hard to tell which ones is right.
