How to get into GW:EN Preveiw Event?(Preordered of Amazon)

I just preordered Guild wars eye of the north from amazon for $40. It says you get the bonus weapons and a chance to be in this weekends preveiw event. Are they gonna send me a key to get into it via email or through mail or what?

Has anyone else preordered it off amazon, and if so how did you get acces to this weekend's preveiw event?

~Thx~

You need the Pre-Order Pack. Just pre-ordering the game doesn't do anything.

had same problem i communicated with amazon they were having problem with their suppliers and didn't have any i got a 3 dollar discount on my next order and seeing i paid 1 dollar for it. i got my money back. instead pf posting here id recommend talking to amazon
