I did for my shower my sister put in the card that I registered at babies r us and target that's how your guess will know where you register at
I also registered at babies r us. It's easy you just go around zap things them people just look up your name and bam the list is there.
Yes you put everywhere you registered om your invite(:
I added star shaped post its inside my invites to let people know where we registered. Check products at target and Walmart the have some I've the same brands for cheaper prices than babies R US.
