I have been reading stories online of people not getting RSVPs back and having people show up who never responded to the invitation. You would think that a self addressed stamped envelope would be enough to encourage people to respond, but it seemed others are having trouble with this. To prevent people from not including their name on the RSVP I have numbered them all. I was wondering if anyone thought it was too tacky or unseemly to use this numbering to create a raffle. Randomly picked from those who respond by the requested date will receive a $25-$50 Visa gift card. It seems to me any couple would be willing to spend $25-$50 to have an accurate guest count. I just didn't know if this would come off as horribly unrefined.
