The folks over at Mightyape are offering a bit of a bargain, for one day only. If you somehow missed the massive Steam sales over the new year period, or maybe you're just a console person, have a browse - it goes up to 80% off.
Whether it's on the massive Steam sales, or in a situation like this, and I see a game that's discounted from $110 to around $60, I think, "Great. They've gone and made it the price it should be. The price before a ridiculous mark-up is applied that we only have to tolerate because we keep paying it."
But hey, you may as well get it cheaper than usual, and there are some genuine deals in there.
Here are some quick ones we spotted:
Dark Souls - $20
Dragon's Dogma - $31
Saint's Row: The Third - $7
Batman: Arkham City - $23
Mass Effect 3 - $26
Portal 2 - $20
Those probably won't last. Check out the sale here. Happy hunting!
