I am currently registered at Bed Bath and Beyond as well as Amazon and Target. I am going through and updating my registries since my shower is a month from today! I have a few duplicates between the three separate stores. Should I only register for certain things from each and delete any similar items? Or just leave it that way (I have quite a few guests that live in BFE and don't really order online, so they will probably go to Target or BBB but IDK which) and return anything we get duplicates of? Sorry if this is a dumb question!
