I have one product that has free shipping if two or more products are purchased. I can do this if only that product is selected and no other products are being purchased at the same time.

The problem comes when other products are added. The Flat Rate shows the $9.00 Best Way (not checked - should be) and the Free Shipping is checked (should not be visible).

The rate is $9.00 no matter how many products are being purchased. The Free Shipping should not show up on the Shopping Cart on Step 1. How do I make it disappear?
