Bloomingdales- http://bloomingdales.weddingchannel.com/catalog/fds/blm/content.action?key=registryGifts -apparently these are expired now, but bloomingdales hasn’t taken them down yet. 😡  When they have a new page up I will make a new post.

You will want to complete the ones that say “Gifts With Registry”, not gift with completion. All you have to do is add the products to your registry that the forms require.  After you do that you mail in your form with a copy of the registry and they send you the gift.
-added- If you have done these from the other posts, there are some duplicates that you cannot do again.
