Where should you include your registry info?
Traditionally speaking, you're supposed to tell your guests about your wedding registry by word of mouth. It's considered impolite to include registry lists or gift information of any kind in your wedding invitations, even though friends or family may tell you that's okay to do. You could offend your guests this way.
There's an easy way to get the word out. Once you've registered, provide your parents, your wedding attendants, and anyone else close to you with a list of your wedding registries, and how to contact them online or in-store. Your wedding website is a great place to post this information. (You can set one up for free here and your WeddingChannel.com registries will auto populate there as well.)
