Groupon offers Resident Evil 6 for PlayStation 3 or Xbox 360 for $19.99 with free shipping. (Amazon charges the same for its Prime members.) That's tied with last month's mention and the lowest total price we could find by at least $8. (It's also the best deal we've seen for the PS3 version, and within a buck of the all-time low for the Xbox 360.) Sales tax is added where applicable. Deal ends today.
