Warlords of Draenor Pre-purchase
The Warlords of Draenor expansion, the game is expected to see a release in Fall of 2014.
As usual, Blizzard is offering two digital versions of this expansion:
Standard Edition for $49.99 and a Digital Deluxe Edition for $69.99 that offers additional in-game items in Diablo, WoW & Starcraft.
As I mentioned several times, regardless of buying the standard or digital deluxe edition, anyone is entitled to one free character boost to one of their existing or freshly-created characters to Level 90. This feature is available immediately upon pre-purchase, so you can play the boosted character prior to release of the expansion. If you wish to boost additional characters, you can buy the service for $60 each.
Veteran characters, that's if you're boosting characters of Level 60 and above will also get a boost to their professions. Here's a tutorial for the boost.
