Best Buy has BioShock 2 on sale for $9.99, until the end of June. I believe it's for all platforms. (X360 and PS3 for sure).
I also noticed Amazon.ca also had it listed for 9.99, but currently it looks like only the X360 and PC versions are at that price. The PS3 version has gone back up to $18.xx.
