I have always charged mileage out of my home county.  The IRS is allowing a 50.5 cent mileage deduction so far this year.  I have been charging 50 cents a mile since right after Katrina hit and the gas prices spiked.  If gas goes up to $4.00 a gallon, I fully intend to raise mileage prices again.  We cannot continue to lose money driving all over creation to work.  Everyone else in the world is charging a fuel surcharge.  I send all my work out by UPS Ground, so I can track it and it will be delivered the next day, and UPS is now charging a fuel surcharge, so that is another fee.  Of course, I charge my clients for this too.  I don't eat any costs.  Have a nice day, and drive safely.
