The discount is automatically taken at check out. I guess that'll be Amazon's way of making sure that the purchase is being made from a Prime account. Even though the Prime service has been available for a few years now, I think that now is the time to really step in and become a member. Not only do you get this awesome discount, but you'll also get the streaming service, the music service, the unlimited cloud storing, as well as the free 2 day shipping. Man... if only this discount was available when Rock band 4 came out... lol
So what are you planning on getting 20% off on? Dark Souls III? The Legend of Zelda: Twilight Princess HD? Let's hear it in the comments, friends! Later!
