The Blizzard Store is having a sale for this week only: The BattleChest (which includes vanilla WoW and The Burning Crusade), Wrath of the Lich King, and Cataclysm are $10 each. These prices are for either the boxed games or the digital downloads.

Blizzard did something similar just before the release of Cataclysm. Severely reducing the barrier to entry for the coming expansion was obviously a success.

So if you are trying to get friends and/or family to join you in Mists of Pandaria (or want another account), now’s the time to do it. The sale ends July 9.
