I just received my RSVP cards and my address is missing my apt number! The printing company isn't willing to reprint another set, and they're making me reorder them. I don't want to waste more money on that company so I was wondering if I should just leave it alone and have the mailman deal with it, or use the embosser that I have to put the correct address onto the flap of the envelopes. Will it be weird to have the address on the envelope twice? In the front and back?
