Preordering Pack Question

I just bought one. I was wondering when I would receive the 10 day trial for all 3 Guild Wars Campaign? Shouldn't there be a key for that? Or is it only for use on my account, even though I have bought all 3 games way before.

Thanks for those answering my question

FYI- /bonus works . You can get the 3 bonus items for preordering

It seems to add those keys automatically to the purchasing account which is ok I suppose if you just want to try out a campaign you don't own already but sort of lame if you wanted to give the keys to a friend,

I saw a trial cd in a store the other day. It was for all 3 games and it cost like $5 or something. That should be free, I think the store was trying to make a few bucks.

The key is for your account. It's in case you are one of the many people who doesn't yet own all 3 games.
