What does Earn 5x, 10x mean?

Our Points program allows you to earn multiple WOWPoints per £1 spent. So 10x or 15x WOWPoints offers mean that you will earn 10 or 15 WOWPoints respectively for every £1 you spend. For instance, if you were to spend £100 at a merchant where the WOWPoints Offer is 15x WOWPoints, you will earn 1,500 WOWPoints for that transaction.
