100 oz. Dreft Baby Detergent for $14.95 on Amazon (beats Costco's price!!)

Amazon has got this 100-oz. (total) pack of Dreft Stage 1 Hypoallergenic Liquid Baby Laundry Detergent for as low as $14.95 (15 cents per ounce) when you stack an online coupon with Subscribe & Save discounts. This price beats Costco's price on Dreft Baby Detergent, ounce for ounce.

First, "clip" the $2.00 online coupon on the item page. Then, the pricing works out as follows:

• $16.95 - $2.00 coupon = $14.95 (15 cents per ounce) with the 15% Subscribe & Save discount (if you can take delivery of 5 or more active subscriptions in one month).

• $18.94 - $2.00 coupon = $16.94 (17 cents per ounce) with the 5% Subscribe & Save discount

Both of these prices beat the Costco price of $19.99 for 150 oz. or 18 cents per ounce (see below).
