So i'm getting ready to send out the invitations and I know it's going to cost me 65 for the postage on the outer envelope because I had it weighed. But the place where I had it weighed, said my pre paid postage rsvp envelopes which weighs next to nothing cost 65 as well! Are you kidding me? 1.30 each in postage fees? The has station postal service says it's because the rsvp are smaller than the letter normal size envelope. grrr. I remember getting invitation for birthday parties and it was stamped with a regular stamp and smaller than the letter size envelope.
