I know a lot of people are curious about this and planning how they can use it... I just got mine! I registered even though we're not having a shower & put my due date as 2/13 instead of 2/26.
The discount is for 10% and is valid until 5/3, so assume maybe 3 months from your receipt of the postcard? It is a simple postcard, so keep an eye out; it seems they send it about 2-3 weeks prior to your due date as you enter it in their system.
Valid one day only, excludes diapers, formula, Bugaboo, Baby Jogger, video game hardware, iPods, RobotGalexy, netbooks, gift cards, Kiddie Kandides, Motherhood Maternity, Buyer Protection Plan, phone orders, special orders, assembly, breastpump rental, delivery, and shipping/handling.
Offer valid only for merchandise added to registry prior to your registry event date. One coupon per guest.
There is an online code listed.
