I have found the prices at the Marathon station to be quite competitive. The station is a bit off the beaten path, as it is located on a frontage road, near Cub Foods. The cashier was quite friendly on my last visit. The total price for my gas was $40.02, and the cashier offered the two pennies with a smile when I presented $41.00. The store is rather small, but a nice selection of beverages and snacks is available.
