Otherwise, another great option to save money on diapers is signing up for Amazon Family. You have to become an Amazon Prime Member (which means paying $99/year, however you can Try Amazon Prime with their 30-Day Free Trial first!) but you will get free two-day shipping on millions of items and unlimited music and video streaming along with your awesome diaper savings of 20% off diaper subscriptions! Plus, you can get a 15% Amazon Baby Registry completion discount. The diaper boxes from Amazon are also bigger and will cost less per diaper often than your local stores, plus you won’t have to spend gas to go pick it up!
