Hey guys i have theory. So at this moment i have a trial account and i have gotten my character to 20. Just recently though i obtained the World of Warcraft game from one of my friends who doesn't play. He happen to have bought the game and installed it but never actually played. However, with the discs came two 10 day trail passes. The instructions on the back read to borrow the discs from someone, install them and enter the code. Although im wondering if i installed the discs and logged on with my trial account email and password, will i be able to enter the code and somehow extend my time? Let me know and thanks for your time!

My understanding is that you have unlimited time with the trial system, just a level cap. So you can play for as long as you want, but never reach past level 20. If that's the case, using the trial discs would have no benefit (and I'm not even sure if it would work, to be honest).

If you're really enjoying the game, just buy the full version. You can usually get it for under $30 (don't worry about the expansions yet). That will allow you to level to 60, and also do a heap of other things Trial accounts can not; be part of guilds, trade, whisper, etc. All the fun stuff!
