This seems a good deal. You get choice of 2 from 3 games for free plus free HDMI cable.
Also you can then buy another game for only £10 (e.g. Need for Speed) and a Blu-Ray DVD for £7 (e.g. Spiderman 3).
Free postage too.
(Sorry can't seem to get the right link but, if you search on "PS3 bundle" you should find it)
