Okay, so I got this idea from because she's a genius.

I have no interest in completing the achievement. What I am after is the prize for completing it.

So I'm offering 200m for you to be able to get the achievement on your account for half off (yay) and once you're done, you send me the book prize (yay). Everyone wins. If you've been considering going for the achievement, now's a good time to go halfises!
