Imagine how embarrassed we were when we found out what Cyber Monday actually referred to! Luckily, we learned our lesson in time to cruise the internet for savings, rather than ill-advised virtua-trysts.
Amazon's probably your first, best stop, with Marvel Ultimate Alliance 2 for $30, Metal Gear Solid 4 for $15 and more on the way. Amazon's also offering $20 in PSN credit with the purchase of qualifying PS3 games. Gamestop's putting out a good spread too, with $20 off LittleBigPlanet and $25 gift cards on plenty of games including Tony Hawk Ride and DJ Hero. The Guitar Hero Store has slashed prices on a ton of bundles. Quite a few retailers have discounts you can use for video games (or anything else you're buying) through Google Checkout as well.
