Place to buy buddy keys, or a trial?

Rallycart

Hello. I used to play AoC back in June and July, and was wondering if there is a place that sells off cheap buddy keys, or maybe a place I can get a trial? I am not ready to resub, and just want a free/cheap way to check out the game again. So, if there any place like that? And please, don't say E-Bay or something, because I simply don't trust personal sales. I have check places that sell CD keys online, and have turned up nothing.

Thanks for any help that you can provide!
