I just popped into Tesco to purchase Red Dead Redemption (as I didn't pre-order), and with every chart game (bar the exception of "Blur"), you receive 800 free Xbox Live points. The 800 points boxes were stacked up amongst the chart games, and the pricing for each chart game was in the colour yellow with the 800 points offer displayed.
800 Microsoft points usually cost around £9.99, so this is definitely a good deal, especially considering the chart games can vary in price between £20-39. I can't find this deal online after looking, but it's still worth popping in to your local Tesco to check.
I noticed someone posted this exact same deal, but had it labelled as Spam and the thread closed. Strange.
