Argos have the ps4 slim for £199 but you can build your own offer with a free game and controller. I got horizon Dawn and a magma red controller so I'm pretty pleased with the overall price for all of it.
Reports in thread of people using media code 16937 to bring the price down to £189.99 at the tills in store... (thanks evaduncan & others)
Games seem to include:
Horizon Zero Dawn
Call of duty infinite warfare
Resident evil 7
Uncharted 4 A thief's end, launch edition
NiohHorizon+Black controller bundle now available from JL - £199.95 +2YR Guarantee
