Well it was $8 only for ps+ members. I unfortunately didn't have plus at the time so I missed out, but now that I have a ps4, and some amazon credit, Im able to a physical copy which I can trade in for another game unlike owning a digital only copy.
I am old school; need the physical copy. I'm cool with digital music but when it comes to games, movies, or books, I want the hard media. Not going to change for me.
