They are offered as freebies with purchase and if you already had them from RDNA you get a $20 store credit. They gave me the credit even though I hadn't purchased all 4 modules. So I picked up the Wolf 2.0 for Poser and spent nothing plus I got modules 3 and 4 of Render Studio 2014 free as well. It was a pretty sweet deal for me. I do have Studio 4.9 downloaded although I won't be using it.
