To take part in Refer a Friend program, all you have to do is visit the Refer a Friend page and enter your friends' e-mail addresses. They'll be sent a personal invitation for the 14-day free trial along with a 25% discount on the full price when they buy a digital download copy of the game from the Codemasters e-store.
For each friend that creates a subscription, you will earn a £5 or 5€ Amazon voucher. It's as easy as that!
