I registered at BRU just so I could get the completion discount. You'll get a card for 10% off anything on your registry that is left, so add anything you think you may buy there. This is the only coupon you can apply with other coupons according to the lady who set me up. So you could use 20% off carseat and 10% completion coupon together for example. It does exclude quite a few brands though, as usual. I think Target also offers a completion discount.
