With the upcoming release of the Wrath of the Lich King expansion, Blizzard is offering incentives for subscribers who recruit their friends to sign up and join the massively multiplayer online role playing game addiction.
Found through a player’s account page, Recruit A Friend allows subscribers to send their friends a code for a 10-day free trial. An experience bonus is immediately available with the transaction, as well as additional bonuses once friends purchase game time.
Referal Bonuses:
