The U.S. Govt has thousands of vehicles in use across the country. One cost-related item about using these vehicles is that the GSA credit cards do not work at lower cost fueling locations like Costco and a number of grocery retailers. It is not unusual to see fuel prices at these retailers 10 cents or more less per gallon than current GSA credit card retailers like major oil company outlets. This issue has bothered me as a taxpayer for years.
I recommend finding a way to permit GSA vehicles and their associated credit cards to be used at Costco and other grocery fuel retailers to help save over a year's time, likely millions of dollars in fuel costs.
