We just received a monetary gift via our honeymoon registry from someone who is not (yet?) invited to our wedding. He is someone I occasionally do business with and is the realtor who helped us find and purchase our home earlier this year. I have a thank you note written to him, and realized I don't have his address because, duh, he's not on the invite list.
He's not somebody that was a must-invite, obviously, but now I'm wondering if we should include him (invitations are going out next week) and how to tactfully ask for his address, whether it's for just the thank you card or the card AND an invitation.
