Hi Lat9,

We're on 1.7.2 And its configured (and always has been) with our shipper number, key, login and password.

The shipping rates shown in ZC are much higher (double) those provided when we ship the same items using UPS's native WorldShip client. WorldShip is the UPS desktop client that we use to generate shipping labels from ZC orders. WorldShip is configured with the same shipper number as UPS XML. It doesn't require a login and PW and API key as does UPS XML, BTW -- only the shipper number.

Having reviewed the change logs in UPS XML in 1.7.3, 1.7.4 and 1.7.5, I'm not seeing anything that would account for this discrepancy.

Thanks for any insights. I also going to turn on debug of UPS XML, see if I can glean anything from that.
