You receive the digital copy which is a code. You go to UniversalDigitalCopy.com and you enter the code, which I will send promptly when the auction ends.
I am sorry not sure if this is considered SD or HD. It has Blu-Ray 3D plus Blu-Ray plus DVD plus digital copy ultra violet. If you win the auction and can't use it I will refund the credits, as its unclear to me from the box.
