Exclusively for Prime members with Amazon Family, Amazon offers the Pampers Swaddlers Size 5 Diapers 124-Count Economy Pack Plus for $17.43. Order via Subscribe & Save to cut that to $13.94. With free shipping, that's $11 below our October mention and the lowest total price we've seen. (It's also about $3 less than you could currently expect to pay in local stores.)
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 Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
