I haven't heard from anyone requesting a copy of the price sheets I referenced in my original post, but here's a little more information for those that might be interested.
First of all the card you receive through TSD Logisitics is a EFS fuel card, which is the card that most commercial drivers use. The discount varies by the total amount of monthly fuel purchases. So obviously TSD put this program together to increase their fuel purchases.
TSD purchases the majority of their fuel from Loves so that's where the best discounts are.
The following is pricing from some randomly selected Loves locations (the Gas Buddy pricing is just the lowest I found for each location):
