Ever heard of alice.com? I found out about and got some diapers from them. I like that it’s free shipping and although most online sites would be more than B&M stores, alice.com isn’t. If you sign up here to start saving you’ll get a $10 credit in your Alice account once you spend at least $50 on the site.
I highly recommend heading to “Other Ways to Shop” and then “Best Deals” to see what you can get for cheap with free shipping included.
