Ratchet and Clank Future: Tools of Destruction and Gran Turismo 5 Prologue, two premier PS3 exclusives, are now on sale for 75% off at the popular North American retail chain, Target.  The games' prices have been axed from $60 and $40 to $15 and $10, respectively.  It's likely Target is putting these on sale to make way for the Greatest Hits editions, which are due to hit shelves any day now.

If you're missing either of these titles from your library, now is the time to pick them up.  Even more so for Ratchet, with the sequel to the game due out this fall.
