Just ahead of the Black Friday shopping extravaganza, Valve's digital distribution service, Steam, is coming through with a massive "Early Holiday Sale" event that will let you expand your PC games library on the cheap. The company will be offering big discounts on a different set of games every day for the next five days, as well as special prices on various publisher packs.

Today's sale features deals on seven titles, with price cuts ranging from 25 to 80 percent, including Batman: Arkham Asylum for $24.99, Far Cry 2 Fortune's Edition for $9.99 and Dragon Age: Origins for $37.49. You can also pick up either the LucasArts Premier Pack or the THQ Complete Pack for $49.99. This offer will run until Friday at 8 AM PST, at which point a new set of deals will become available, so definitely keep an eye out for more.

Before pulling out your wallet, though, be sure to check out some of the deals being offered by the competition. Direct2Drive's "All Killer, No Filler" sale, for example, takes 50 percent off the prices of Crysis Maximum Edition and Resident Evil 5. Over at Impulse they have put over 40 games in their download library on sale. Meanwhile, EA’s own store will be selling every single downloadable PC game with a 30 percent discount until Monday, which includes The Sims 3 for $34.96 or FIFA Soccer 10 for $27.96.

If you have had your eye on some of the holiday season's most anticipated games, now is the time to buy.
