I just found this on Numrich Gun Parts site:
Notice to all Customers:
Effective June 5th, 2006 UPS will be removing the fuel surcharge cap on their small package air service. The initial impact will result in a 3.5% increase on all air shipment charges. This increase will appear on any UPS air services that you may request.
The fuel surcharge cap on UPS ground services remains unchanged, but the surcharge will increase from 3.75% to 4.25%. For the present, Numrich Gun Parts will absorb this increase. Please be advised that should these charges continue to rise we reserve the right to increase our shipping charges as required.
Sincerely,
Numrich Gun Parts Corporation
