Blizzard games and expansion packs can be purchased directly through the Battle.net website using the Direct Online Upgrade option. Direct Online Upgrade is a fast, easy way for new players to get started or for veteran players to pick up our latest games and expansion packs.
If you’ve already attached a Starter Edition license, you’ll see the option to upgrade that Starter Edition on the Game Management page in Battle.net Account Management. Once you complete your purchase, visit the Game Client Download page to install the game.
Note: Some game features may take up to 72 hours to become available after the digital purchase is completed. The World of Warcraft Starter Edition article contains a full list of these features.
