Combining Your Boxes

Why is this good?

The best way to explain this is with an example:
Suzy, who lives in Brazil, logged into our website and received our address and her customer number. She clicked the links of the stores on our site and bought from 3 different stores. Each package weighed 3 lbs. See below for comparison of when she shipped to herself directly from the stores VERSUS shipping to Shipments4you + combining her packages + 50% shipping discount.
