Kelefane: What if I bought a $20 Blizzard Gift Card to buy Diablo 2 + LoD with, would that be enough? Or would I need enough to cover taxes also?

USA here by the way.

Edit: I meant off the Blizzard website.
I'm afraid you cannot use a Blizzard gift card on, since and are different platforms.
If you want to place an order on, the purchase has to be done directly through our service.

For any related questions I'd recommend contacting the support directly :)
