It's crazy but I added all the registries we have thus far. I warn you - we've got a bunch of registries and not much items. I'd avoid Target entirely for the moment; we registered for a few bathroom items there but I don't believe all of them are exactly the model that we are looking for. Amazon, Macys, Bed Bath & Beyond, and of course Sandals, should be up to date (if not complete.)
We know our list is kinda all over the place, but that's what happens when two people come together who've accumulated years of "stuff" already prior to marriage. Hope it helps for those asking about registries. We will try to complete these lists at some point VERY soon.
