My wedding is about 3.5 weeks away, and I sent out my invitations about 8 weeks ago and now I am hearing that some invitations haven't been delivered, and we have a received a ton of "not coming". I need a minimum # of people to hit my food and beverage required amount and my current list of "yes" responses is about 40 people shy of my required #. Is it too late to send out more invitations and pretend the post office is slow, or call and pretend the post office lost them - which is actually true in some cases... HELP????
