SO, i won a contest at aionsource just before christmas that got me a retail EU aion key.
I am totally fine with just giving it away, however there are just 2 simple conditions.
1) I want that person to play through my referal.
2) I want that person to be absolutely sure he/she will play retail and hence purchase one month of game time after using my key to upgrade the referal account.
That way i get a free game month and some items, and so does your trial account.
So basically, i'm saving you the cost of a retail copy, but it will cost you one month of gametime.
