Shell Gas Station really wants customer to try their Car Wash

With electronic boards, gas station can change fuel prices at anytime. This particular Shell Gas Station has some interesting pricing strategy, and this is not the first time I spotted the pricing.

Unleaded Fuel Pricing with & without car wash.

$7.119/gallon of regular unleaded fuel which is more expensive than its “Plus” & “Premium” counterparts. But if customers also pay for car wash, the price is 5.749/gallon of regular unleaded fuel.
