You can also get the details from their website, I hope its a more helpful for your company and you to purchase a fuel cards.
I just went to NASTC class and getting their discounts now. I had fleetone before and now I love the discounts. I have no regrets. I paid right at $0.30/gallon (+/- $0.003) off in Denver on 11-5-2013. I believe cash price at TA was 3.859 and we paid 3.561.
