GAME are offering a extra £20 trade-in credit when trading in selected consoles and tablets (Xbox 360, PS3, Wii U, 3DS, Vita) towards the purchase of a PS4.
I traded in my Black Wii U yesterday (trade price: £190) and got the additional £20 credit (£210) bringing the price of the PS4 down from £349 to £139 at launch. Good times!
Emailed GAME and they said:
"Offer ends at the end of Monday and not Sunday midnight"
GAME DO HAVE PRICE PROMISE!
Thank you for your email.
I can confirm that we have no control on the prices of this console. This can be changed at any time by Sony themselves. If this price was to drop on release date then you would receive this console at the lower price.
