The $19.99 purchases classic World of Warcraft only, Shauwk. The additional costs are as follows:

• Burning Crusade expansion -- $29.99 USD
  
• Wrath of the Lich King expansion -- $39.99 USD

You can save approximately $10.00 by purchasing the World of Warcraft Battlechest from a retail store for $39.99 USD, which includes both classic World of Warcraft and the Burning Crusade. Included in the Battlechest are strategy guides for each game, which could be somewhat helpful for a new player.

Wrath of the Lich King is completely optional at this junction since Death Knights cannot be created until there is a level 55 character on the account. However, you will need this expansion to access any of the Lich King content (i.e. Dalaran).

See you around Azeroth!

Be sure you are purchasing an UNUSED copy of the game. If you are purchasing a "used" copy of the game, chances are the authentication keys have been used by another player, and therefore cannot be applied to another account.

You can use your brother’s discs to install the software onto your computer, but doing so does not give you the ability to access that content. When you purchase the game itself, you are in essence purchasing the authentication key which unlocks that particular game content. Subscription fees are an entirely separate purchase altogether.

Q u o t e:
hmm alright ... i think i will get 6 month recurring... is there a way to get 6 month without recurring though?

If a credit card is added to an account for a subscription, the credit card will automatically charge unless removed from the account. As an alternative to recurring subscriptions, Digital Game Time may be purchased through the Blizzard Online Store in 1-, 3-, or 6- month increments and will not recur.

If you wish to purchase Digital Game Time you may do so here:
