I just downloaded the bazaar tarball and installed it. I verified that the files recently changed have approximately the same timestamp as the the changes listed on the bazaar page. Tested the USPS shipping quote. The review cart page does not display any shipping charges. I displayed the request to the USPS server and the USPS server reply per the suggestion made above. Both look complete and correct to me. However, the shipping charge is not processed and displayed. I have no options for shipping charges.

Sigh. I am ready to go live, but I need to have either flatrate or USPS shipping working before I can do so.
