So you are in Gainesville and you went to send some urgent mail in your own interest (personal) and you are honest enough to not use your department account. What's the cheapest/most reliable option?
For US, use FEDEX from Shands Hospital
-take the walk to the West Wing Entry to the hospital, the one by the the crossing corresponding to Mowry Road
-when you are almost ready to get into the building, look at right, you'll see a ramp (and a FEDEX truck in front of it)
-take the stairs to the ramp, get inside, ask about FEDEX.
You want to bring your package after 3 pm (and before 4 30 , to play safe) and pay at the cashier. The pay difference between that and putting your pack at a FEDEX box is quite significant: a next day priority would be 21.50 at the box but 6 .50 at the cashier!!!
