Just found out that the Christmas cards I mailed this week may all come back for extra postage. Seems the USPS can’t wont run square envelopes through their “machine” and so they want twenty extra cents, on top of the 44 cents they are already charging, to mail a Christmas card that is perfectly square.
What a load of crap!
