Do you have an Amazon Mom account?  If you don’t you should. When you sign up for Amazon Mom you get a discount on diapers and wipes but the BEST thing about Amazon Mom is you get at least 3 months of free 2 day shipping on items marked “Free Shipping with Amazon Prime.”   You don’t have to be a mom set up an account.  The only requirement is that you are a caregiver to a child.  Sign up here  Amazon Mom.
