How does UltraCart calculate shipping costs?
UltraCart can calculate shipping four different ways: real-time, by order subtotal, by order weight, or by order item. The most popular form of shipping calculation is real-time. Our real-time integration with Australian Post, Canadian Post, DHL, FedEx, UPS, USPS, and Watkins allows for the most accurate shipping estimates possible. UltraCart can even handle oversized packages and multipackage orders properly.
