this is about the cheapest i have seen a decent brand 4gb kit of DDR3 ram in a long time (excluding dodgy play.com deals!). i presume it comes with a lifetime warranty through kingstoon because nearly all of kingston's ram do have lifetime warranties.
use super saver delivery for free delivery.
maybe this is just the start of the price war that was mentioned with the kingston 3x2gb kit yesterday, i really hope so :D!!!
