How does Wawa credit card work? 5 cent off or 10 cent off per gallon of gas purchases?

How do I know if I get 10 cent per gallon off or 5 cent per gallon off? I applied for this card for the special promotional ongoing 5 cent or 10 cent off, however I don t see anywhere that I get 10 cent or 5 cent per gallon off.
