Steam cuts up to 90% off a selection of downloadable games for Windows or Mac during its Summer Sale, with prices starting at 39 cents. It also offers a selection of daily deals and flash deals. It's the largest sale we've seen from Steam in over a year and many titles are at the lowest prices we've seen. Deals end at 9pm ET.

A best bet is downloads of GRID 2 for Windows for $29.99. That's the lowest total price we could find by $7 and the best price we've seen for this game.
