I don't think they work online. I looked this up last week. I think you either have to order your items full price then take them into the store with thte coupon and get a refund for the 20% off. Or you can go to the store and they will order it for you with the discount. There is no where on the website to add a code.
If you wait just three more weeks, everything left on your registry (two weeks before Due Date) is 10% off, but I would think in-store. Not sure though, good luck! I just got my mailer over the weekend, the cover has a brown haired toddler girl surrounded by bottles. Keep an eye out!
