Just wondering if you guys have heard of this. I recently heard about it from a friend who's getting married next year and is planning to do this. Apparently the bride and groom throw a party/dinner/whathaveyou and everyone invited is supposed to bring a bottle of something for them to "stock up" for their future wedding. I mean, really, why not just have a BYOB wedding since that's essentially what you are doing?!! Ugh.
