Q u o t e:
1st when will the digital download will be aviliable(meaning same time or a few days after etc)
2nd one time i used a prepaid credit card to purchace something from blizz store, if i get another one OF THE SAME TYPE could i get a digital download with it come dec 7th (or when the digital one is out)?

It has not been determined when the Digital Download for Cataclysm will be available for purchase, Shlian. If you would like to upgrade immediately upon release, you may wish to consider purchasing the game from a local retailer.

Prepaid credit cards may or may not be accepted for purchases through the online store. Typically our system will not accept them due to address verification issues. Unfortunately, I cannot guarantee this type of card, or any card for that matter, will be accepted at the time of purchase.

My apologies, all.

See below for the information concerning the availability of the Cataclysm online upgrade.

Q u o t e:
With World of Warcraft: Cataclysm coming December 7, we're pleased to announce that for the first time, you'll be able to pre-order the expansion from the Blizzard store, download all of the installation DVD's content in advance, and start playing the moment we turn the servers on at midnight, Pacific time, on December 7. Pre-orders will go live soon, so stay tuned to http://blizzard.com for more information.
