If you use the TrepStar retail order page, you may now change the amount of shipping/handling your retail order customer pays.
Lowering the amount the customer pays for shipping and handling will increase sales. You may now absorb some of those fees from your net proceeds. In other words, set your retail price up a few dollars, and set your cart settings to absorb a few dollars in shipping costs (so your overall net proceeds remain the same).
