The company we ordered our save the date magnets from sent us about 40 extra and didn't charge us for them. We have a few people who we're inviting to the wedding who we didn't send a save the date to. Can we put one in with their regular invitation or would that be bad form? The magnets are really cute so I'd hate to waste them. At the same time, I don't want people to feel like they weren't a high enough priority to get a save the date when we originally sent them out. What does everyone think?
