Far Cry 4: Kyrat Edition (Xbox One) is $39.99 at Best Buy right now, $31.99 w/GCU.
The PS4 version is $65 "on sale", so not a good deal there.
Could be a decent pickup. Comes with the Limited Edition version of FC4.
The lowest this has been New was $30 I believe. With a GCU membership this brings it close enough if any are still interested.
