How do I get "50% off ALL apps and expansion packs" like the banner ad promises?

  • Hi! Positive Grid is running a banner ad across the smartphone version of its website that says "50% of ALL apps and expansion packs". There is also a counter that expires in two days.
    However, these prices are not reflected in the cart when I go to check out. Only one app appears to be 50% off. Is there a coupon for the 50% off?
    This is weird because Positive Grid put the word "all" in all caps... so I'm taking them at their word that ALL apps are 50% off. I would be really disappointed in Positive Grid if this is just click bait.
