I registered on amazon.com. They sent me an Amazon.com Baby Registry welcome email with all kinds of information. It says you get the completion coupon 30 days before the event. Good luck!
You get your completion coupon 30 days before the event date. Only items from Amazon.com baby department are eligible and the purchase has to be made in a single transaction to claim the discount.
Still waiting on mine. My sister had her baby last year and she did tell me to put the "event date" on all registries at least 2 weeks early so I'd get the coupons early. Got my BRU one last week!
