Hi Bruce, and thank you for posting to our community.

I believe we resolved your issue via email but I wanted to post here as well for others to see.

Typically a discrepancies in rates can occur due to a failure in the Ready to Ship page updating. The easiest way to force update the Ready to Ship page is to click the 'Update' button next to the weight or dimension fields at the bottom of the carrier options.

Even the if the 'Update' buttons are greyed out, they will still update the page when clicked on.

Thank you and happy shipping!
