40% off RS2014 PC/Mac ($36) and 25% off most of the older DLC on Steam right now. Still updating, so not sure if more DLC will be discounted or not. Highly recommend this version over the consoles because of the easy customs. Get some.
Since it's Steam's Thanksgiving sale -- wait for a flash deal, the last day of the sale, or for it to go on sale for 75%+.
