I'm still polishing the Subscriber's system. One problem that has come up is, how do subscribers get hold of downloads that were released before they subscribed? Surely they shouldn't have to pay full price?!
So now, if you visit the store as a subscriber you will be given a code which gives you a 50% discount! All subscribers get 50% off the price of existing downloads. I'll streamline the system soon, just working on the technology. Meanwhile subscribe to claim your models half price.
