Hello,
Our UPS ground calculator is still pulling quotes straight from the UPS website, although that information can change depending on your product settings. You might find a difference between the result we get from UPS and a more detailed quote that you get from them directly since we are only able to provide basic information on the shipping origin, destination, and the number and average weight of the packages for any one order without going into details about whether or not it is a residential or commercial delivery address, etc.
