Now that I have all of them addressed and ready to be sent out I have no idea what I'm supposed to do with them! haha - we have 150 invites to mail so do I just drop them in the box at the post office or do I need to do something else? Would this many invites be considered 'bulk mail'? Sorry if this is a dumb question, but I just want to be sure that we won't have any problems or delays in getting them on their way to our guests..... As always - thank you for your input! ~Katrina
