It was close to the same price for region free BluRay from the UK over a year ago, but I haven’t seen it posted for less digitally in the last few years (from a few searches that I tried).
I believe there are a few movies (Razor, and Blood and Chrome) to make it really "complete" (I have them from Vudu D2D and hope they’ll port over via Movies Anywhere at some point).
