Do you get Parents magazine in the mail? If so--look for the bright orange coupon inside for 20% off a Diaper order at Amazon.com!!
Many of the extra large boxes of diapers are on sale and you can save even more if you sign up for Subscribe and Save!! Subscribe and Save is a program Amazon has where they will send you an order every month or two months or as often as you like. The great thing is that you can cancel it before you get another order with zero problems!
(I did this with the coffee pods for my Keurig and had no problem getting the subscribe and save price for a one time order).
Here's what my cart looked like after the coupon from Parents:
Shipping Method: Two-Day Shipping
Subtotal of Items: $35.88
Shipping & Handling: $22.56
Promotion Applied: -$10.76
Free Shipping: -$22.56

That's .09cents a diaper! Which is a pretty outstanding deal for diapers delivered to your doorstep!!!
