Prior to WooCommerce 2.1, this issue could not be fixed as every order had to be sent utilizing a solo shipping method with an average cost. I had software development shop for them. However, from 2.1 onwards, those purchases can be divided and grouped separately as different packages and can be shipped individually using different shipping methods. These factors can be created by a wide range of understanding of purchases, such as product seller, product category, pricing, and so on.
