Force To Distribution Center
If you need to force an order to route to a particular distribution center when this shipping method is selected, pick the distribution center code from the list below. Please note this will not cause the cost of shipping to recalculate since this routing takes place after the shipping method has been selected. This option is primary used with customer pickup methods.

Least cost routing allows you to adjust a shipping method to another method based upon the actual costs. Let's say that you have a method called Standard Shipping that is $4.95 at checkout, but before you transfer the order to the fulfillment house you need to determine what is the actual shipping method that should be used. Least cost shipping allows you to configure which methods should be rated to change the order to. Keep in mind that it selects the least costly method, but the customer does not see a cost change on their order.
