I noticed that this was in the 5.5 documentation, but is this still available in version 6 and 7? I would like to have free shipping for customers who order more than 10 items. Then, they can get additional free shipping if they order at least 10 more, but no less than 10 more. So if they ordered 11, they would get free shipping on the first 10, but would have to pay shipping for that 1 additional item. But if they ordered 20, they would get free shipping on both sets of 10.
