The shipping isn't using ANY external shipping methods. They are all methods set within Advanced Shipper for specific locations, weights, and order values. I don't really understand why it's doing this as the shipping cost is displayed next to the various checkboxes as soon as you get to checkout. There is no delay in the method cost being displayed on screen.
