I bought refirbished MK2 mini approximately half a year ago which came with Complete 13 Select, that is why I was entitled for this upgrade option. Got lucky to get 30 % Christmas discount from Musiker, which was not available on NI official page. I am very happy I found it😊 Thank you very much. P.S. this product comes with 300 GB hard drive, however installing the actuall files and libraries still requires space on the computer.
