Diapers.com cuts 20% off regular-priced Huggies Snug & Dry Economy Plus cases of diapers via coupon code "20SNUG". Plus, check the eCoupon box on the product page and apply coupon code "BABY13A" in cart to collectively cut a further $12 off. With free shipping on orders of $49 or more (before the coupons), that yields a number of price lows on these diapers. (We saw the eCoupon plus an extra $15 off two cases last week, since expired.) Deal ends February 11.
A best bet is the Huggies Snug & Dry Diapers 246-Pack in Size 2 (pictured) for $49.99 before the above coupons, $28.39 after. With free shipping, that's $0.12 per diaper, $6 under our November mention, and $7 under the lowest total price we could find for this quantity elsewhere.
