Harvey Norman currently offering the cheapest physical price for Battlefield V on PS4 and Xbox One. $66. Additional fees for delivery.
Amazon also offering $66 now but with Harvey Norman you won't have to wait for postage. Elsewhere it's $69 at JB-HiFi and Target for physical copies.
Looks to be that price on PC too. Had a quick look around and seems to be a fair, if not the best price also:
