How much do you have to pay to play world of warcraft?

I started a free trial on World of Warcraft.One of my friends has an account on the game and she said she only had to pay $5 a month.But my dad says it's $15 a month.I'm confused.My dad says he's read a lot about the game online and stuff,but my friend...

is the one with the actual account on the game.So,how much a month do you have to pay to play and why do you even HAVE to pay?

its $15 dollars a month,and I dont know why your friends pays only $5

Yup, it's $14.99 a month plus tax.

It is $15 a month, A cheap form of entertainment when you think about it.

You don't need that thing in your life, buddy. Trust me. I've lost too many friends because of that ''game''. Get a hobby. You can build models in your free time, or work out.

Don't play it. I heard its fun and you'd get addicted. You will be a loser with no friends, at least that's what I heard. And its $15 I think

I think it $15

Im Pretty Sure its $15 a month

I heard that if you play world of warcraft for 6 months you pay £12 somthing
