I usually ship USPS Priority Mail through Paypal for my auction items, but I have a buyer who wants their item shipped Express Mail and a new invoice. I don't remember if Paypal has an Express Mail option on their dropdown menu for USPS, I just remember first class, Priority, and parcel post. Since they haven't paid yet, I can't get into the shipping section of Paypal to check. Does anyone know if I have that option, or do I need to go down to the post office? Thanks!
