This feature has been released and is available in v3.99 now. In the buynow settings there is a new setting titled "Address Type" that will control this. The shipping costs returned from the real time shipping calculator are different based on the “ship to” address being residential or commercial. The “Address Type” setting allows you to configure Automatic, Residential or Commercial when communicating with the real time shipping calculator API to provide a more exact shipping cost. The following "Address Type" option are available:
- Auto - Shipping Calculator API determines address type (Residentual/Commercial) automatically.
- Residential - Sends residential flag to shipping calculator and calculates rates based on “ship to” residential address.
- Commercial - Sends commercial flag to shipping calculator and calculates rates based on “ship to” commercial address.
