I registered at my local BRU on Saturday (I live in PA) and was told that the completion coupon would be sent about 4 weeks before my due date and was for 15% off (they said they recently changed it from 10%).
I recommend later going in and changing your due dates on your registry if you plan on using the coupon to get those last few items before baby comes. They say they send them out about a month before your due date but everyone I know has always gotten them either just about their due date or after.
