We've now activated a feature where you can be notified when an Out Of Stock or Coming Soon item is available for purchase. In the bottom right corner of any Product Page just click (as shown) and enter your e-mail and you be notified when it's re-stocked. The vast majority of sales are re-stocked titles so be the first to know when something you're looking for gets picked up again. This will also let me know what to keep an eye out for when browsing out in the wild.
