How much is the postage on the cards and are there any cards that require additional postage?
Our mailing service is only available on cards which can be mailed with a standard US or Domestic stamp.
Currently, all card formats we offer can be mailed with one first-class stamp, with two exceptions, which require a "wedding" stamp for the square envelope (http://weddingstamps.us/postage-square-envelopes):
- Square cards (folded or flat)
- Circle cards
