I just noticed this today, but didn't see it here. Steam is having a big sale today. Here's the Civ 5 page:

(be patient if it doesn't load as there are so many sales going on, huge traffic problems)
Edit July 5th: As some people posted already, Civ 5 is one of the daily deals today. Everything Civ 5 50% off. Daily deals are just that, this day only so get it while it lasts. Also as the title says the 33% off will continue for the duration of the summer sale, but no one wants 33% off when you could get 50% off.
