A BMW driver at a gas station was confused when he spotted two different prices for the same grade of fuel. Is the unidentified Shell gas station ripping customers off—or is there another, reasonable explanation? Shell, like many gas stations, offers a fuel rewards program. Via email, a Shell spokesperson told Motor1 that prices vary for a variety of reasons, such as fuel rewards and discounts. "In some cases, eligible discounts can be combined, which may explain the price difference shown in the video," Shell's spokesperson added.
