Here is another matrix of TW "Current Shipper" rates & surcharges.
This one is not posted on the web.
I don't know whether anyone needs/uses it, anymore, but I have been keeping it up.
There is a new tab for each change in Current Shipper Rates.
The latest is "200111"

Elizabeth - I forgot to send this to you this morning.  
Jeanette - I don't recall whether I sent this along with the other TW files.
