Ray the amount you owe goes down in percentage to the amount you spend, Lets say you buy $15.10 worth of product twice it would cost for shipping $13.50 total. If you bought one order of $30.20 (double the origional) order you would pay $7.75 for shipping a savings of $5.75 for the same order if orderd in one batch instead of two. This discourages people from making small orders and rewards those who order bigger orders.
