The Splinter Cell Conviction collector's edition has just been reduced in price, from $80 to $70. It's hardly an act of charity, though; you can instead thank some dodgy USB drives for the savings.
According to a "random sampling" of the USB drives, which were among a number of goodies included in the collector's edition, many of them are "defective". Not all of them, mind you, just "many".
With the game out next week it's too late to remove them from the pack, so instead anyone picking up the collector's edition can indulge in a little USB stick lottery. Maybe it'll be broken, hence the $10 saving, and maybe it won't, and you just made $10.
