YMMV Seems to be a targeted deal - only showing when I'm signed in and I have also recently cancelled my subscription.
Just noticed this price drop. Pretty good price for 9 decent quality games a month.
Note that this deal lasts for 12 months only and you will be billed automatically at $29.99/month afterwards unless you cancel your subscription.
Remember to use an OzB referral link if you decide to sign up.
