This year's holiday sales are officially in full swing. Nearly all the digital distribution firms have cut prices across the board, and if you see something you want, you should probably grab it sooner rather than later. Steam's holiday extravaganza ends this Sunday, January 2, and the other outfits will conclude their sales around the same time.
