I understand your frustation - when I was waiting, I got a lot the first week and then 1 during a 3 week time period. I ended up getting about 25 of 61 back. The rest we got calls, FB messages, emails, and word of mouth. It was REALLY annoying. Especially since it wasted all those stamps!
Our deadline is this Saturday and we're waiting for about 10 cards. It's like at this point, you should know if you're coming or not, just let us know so that we can move on! This has been the most frustrating part of wedding planning! The waiting game continues...
