The new Deal of the Day offers World of Warcraft: Cataclysm for only $23.00 while supplies last, or until April 25 midnight.
There are other mind-blowing deals on all Blizzard video games here.
Diablo III Battle Chest includes Diablo II and its expansion Lord of Destruction. I have seen it for $40.00, but in today's deal you only pay $19.99 while supplies last. That's an awesome deal for those who wish to give it a try and learn the lore and gameplay prior to Diablo III.
Warcraft III Battle Chest includes Warcraft III: Reign of Chaos and its expansion Frozen Throne. Only for $22.99 while supplies last. Other Blizzard video games are $10 cheaper.
