Thanks to Myfrugaladventures.com for this pricing of diapers:
You will need to register for Amazon Mom (totally and completely free trial subscription) nothing to cancel and no further obligations. I have selected one size below as an example of the price- but you can select whatever size you need.
Pampers Baby Dry $19.59- Select subscribe and save on the right hand side to get this price. Grab the $1.50/1 coupon here first (log into your account first and refresh until you see it) or it might be right in the center of your screen. That is .12 per diaper for size 3 or like paying $3.89 for a Jumbo pack and shipping is free!
***If you need Cruisers, Swaddlers size 3, Swaddler Sensitive 3 or 4, or an Extra Protection box there is a $3.00 off coupon. Make sure you are logged into your account to see it and you may need to refresh the page a few times before it appears.
