BestBuy has a limited time offer when you purchase the original World of Warcraft MMO DVD. Add World of Warcraft to your cart, then select the Burning Crusade. Select add items to cart button, and you get the Burning Crusade free with the purchase of WoW.
BestBuy is selling the original WoW for only $19.99, so if you want to gift a family member or friend with the game, this is the perfect time.
Newcomers got enough time to level up and catch up once the Cataclysm expansion hits game shops late 2010.
