Head over to the Babies 'R Us website, because right now they have Huggies Santa diapers (sizes 3, 4, and 5) for just $4.98/jumbo pack. If you signed up for a free year of ShopRunner, you can get free 2-day shipping as well. Hurry, as I am guessing that they have limited quanities available!
Also, go through Ebates (my referral link) for 1% cash back.
Go get your "coup" on!
