Just because the Kinkos guys says so, doesn't make it so. I think UPS (the air division) get the discounted shipping (trucker drivers, couriers etc don't). Its an interline bennie. Kinkos should be on top of this, but who knows. I was in the Kinkos behind our layover hotel in HNL recently and they had a sign stating that interline shipping was not avail. 12/16 to some time near the New Year. So they should know about interline shipping bennies. Try going to the local station with your id when shipping.
