Mailing Square Invitation Envelopes - Additional Postage Required
Yes it's true - square envelopes do cost more to mail.
Due to the non-machinable size and shape of square envelopes, the USPS charges an additional $.21* surcharge for square envelopes. Added to the current stamp price of $.47*, each square envelope will cost at least $.68 to mail.
Anything over one ounce requires additional postage as well. To determine accurate postage for your envelopes, we recommend bringing one finished invite ensemble to the post office.
