Oh, I have discovered and fallen in love with Soap.com and diapers.com. Mostly soap.com because I love Target brand diapers. :) It is fabulous for busy people! I love it because I can place my orders on my lunch break, get free shipping, and it ships to my house in just 2 days. Seriously, if you are like me and have a hard time getting to the store- this is fabulous. The prices are very compariable to going to the box stores, sometimes even better because they have sales and coupons.
If you are going to try them out, either soap.com or diapers.com use the referal code crankid and you will get 15% off your first purchase and I will get $$$ for refering you.
Honestly, give it a try!!!
