If it isn't somewhat flexible, it must go as parcel. Otherwise, it can jam a sorting machine. You could have asked for it to be sent as a Non-Machinable Envelope. I don't know the extra charge for the non-machinable marking, but I guess Mark could tell you that. I know it's cheaper to send that way than as a parcel.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
