Just back from Tesco
LA Noire is £25 with any top 20 chart game, in store you can buy 2100 MSPoints with this deal (you can't do this online) so total price is £25 + £18.50 = £43.50, not bad considering most places are selling it for £40.
Other cheap game options which ARE available online aswell:
- Carnival Games Kinect - £19.99
- Marvel vs Capcom 3 - £19.99
- Test Drive Unlimited 2 - £24.99
Didn't check the PS3 section.
