Microsoft's Xbox LIVE deal of the week is available right now. The Project Gotham Racing 4 Premium Challenge Pack, normally priced at 400 points, is available for Xbox LIVE Gold Members for 240 points, a savings of 40%.
This is an insane deal! Prices this low will never come along again in this or any other lifetime. This price is so low, I can only see it as evidence that Major Nelson and the Xbox LIVE staff have gone entirely mad with savings. Mad, I tell you!
Uh. Seriously, though... PGR 4 is an impressive racing title and this deal should be enough to make you dust off your copy of th game and get some racing done.
