Had a bit of a result as when I was in Argos I explained to the manager that the deal splash on the website PS4 page pictured the white console as well as the black but this was still showing as £229.99 so he manually discounted it down for me. In the end I got the white 500gb slim PS4, second v2 white Dualshock and Horizon for £199.99. I also traded in a load of odds and ends at CEX that saw me get Resi 7, UC4 and The Last Guardian with just a £16 outlay.
N.B. I notice now on the Argos website the deal front page splash has now removed the white console and just shows the black.
