I can't say it's the cheapssted one, but for the boxed PC version, it seems it has a good price for AU stock. I paid $30.99 delievered, no sure of shipping costs for other states. Commons down below if you find out.
Seems Cyberpunk 2077 received a lots of positive feedback recently, even throught the bugs are still there. For $31, I will buy the box version to support developers. I will these info helps.
