Target offers the Pampers Diapers Super Pack in Swaddlers or Baby Dry for $24.99. Add six to your cart as a subscription to bag $50 in Target Gift Cards and drop the price to $142.44. With free shipping, and assuming you'll use the gift cards, that's the lowest total price we could find by $57. They're available in sizes Newborn to 6. Deal ends January 14.
Of note, if this is either the first or second subscription order you've placed at Target, you'll be eligible for even further discounts. (If applicable, be sure to pad your order over $125 to ensure you'll receive $50 worth of Target gift cards.)
Be sure to cancel your subscription once your order ships to avoid being billed for subsequent purchases.
