Pelton Crane OCR Rebuild Sterilizer 9 Dia x 18 Deep Z-OCR-R

I work in a hospital, from Alliance, NE. I purchased Pelton Crane OCR Rebuild Sterilizer 9 Dia x 18 Deep Z-OCR-R from sterilizers.com on 2/4/2008.

The salesman I dealt with was Shlomo Savyon.
The salesman, Why am I being billed for shipping, the printout I received from Dr. Ruffing didn't show any. Also, why does it take so long to ship if we order by regular ground delivery. Can you tell me what the cost of overnight delivery would be? Is there any way to have this shipped sooner.
