With the Games for Windows Live client, for this weekend Batman: AA is £8.75.
But there's more to this, if you change the value to Microsoft Points then it comes out at 940 MSP, which is equal to £7.99!
That's assuming you bought them through the dash in the first place, if you've been buying cheaper prepaid cards then it's even cheaper than that!
To sum up: Don't pay in real money. Buy 1000 MSP if you have to, that's only £8.50.
