That's $0.09/diaper and about $5 less than what you could expect to pay in local stores, although we saw it for $3 less last month. To get this deal:

1. View the Pampers Swaddlers Diaper 216-Count Pack for $24.31
2. clip the 20% off coupon on the product page
3. add it to your cart via Subscribe & Save for a final price of $19.45

Note: You must have Amazon Family to get this deal. (Most Prime members get Amazon Family for free with signup; however, some people sharing Prime benefits prior to Amazon Household may not qualify.) Be sure to cancel your subscription after your order ships to avoid being billed for subsequent purchases.
