Tips for adjusting calculated shipping rates
One way to keep your shipping rates low, but still have the rates correspond your actual shipping costs is to use the **rate tweaker** to modify the calculated rates before showing them to your customer. This allows you to share some of the shipping costs with your customers. Keeping your shipping rates lower than your competitors will close more sales.
