If you have multiple registries, did you only include certain items at certain stores? For example, if I have a dinnerware set on a registry from one store, so should I not add another dinnerware set to a different registry? I don't want to have multiples of what I don't necessarily need, but I don't know how to keep track and ensure that guests won't buy one set from one store and another guest will purchase one from a different store's registry.
