its actually not a battery warrenty..unless they have this and i never knew about it
im hoping its the service plan which covers your battery, screen, and to make sure you laptop works as good 2 years from now as when you open it

and they will probably sell to you tomorrow cuz sunday is the ad day and the day when non-media items are released

also dont get a laptop case, its a sign for theives to take your sh*t
