Argos are doing one of their combination deals. Buy a premium with Forza 2 and an Xbox mega pack - you save £90. (Basically you get £20 off Forza and the mega pack (£70) for free).
Mega pack includes steering wheel with separate foor pedals, wired controller, DVD remote, faceplate and stand.
The offer isn't listed under the Xbox premium so search for Forza 2 first and it is listed there.
