Gorgon and Gorgon Extreme not working?

DisparateDreamer

So the Gorgon page http://www.daz3d.com/the-gorgon says that if you put Gorgon and Gorgon Xtreme in the cart together, you will get 50% off on Gorgon Xtreme.

Except it doesn't work.

Either it was a limited promo which it SHOULD HAVE SAID SO as other promos like that at least have said "for the date of such and such, get this at 50% off when..." etc.

Or else the store at daz is being ridiculously broken yet again.

Either way, sale lost :(
