salesmen at best buy = Thieves
It ain't any different than when you go to anywhere else. The extra protection plans are around because a lot of people do need them and use them.
There is more that the extra "warranty" covers other than the battery. Best buy's now also covers accidental damage.
I didn't know macs where also immune to accidental damage.....hmmm that Best Buy employee shouldn't have lied to customer and told him about the force field that deploys when a mac senses it is falling to ground.....
Or how about when he failed to tell the poor older "ignorant" customer how when lightning is coming down from the clouds it says to itself, "hmmm, i better go a different way it's a macbook down there, i'm better of finding a pc to strike."
Just because you may have been lucky so far, it does not mean one day you will not get burned and wish you would have bought the protection. It is only a matter of time.
And by the way, you don't have to wait until your Allmighty and decade lasting Mac battery is dead before you can take advantage of your battery replacement , you can get it anytime after a year. Oh, and guess what? You don't even need to send back your old one....cough cough!!! What! you mean you can keep both? and actually have 2 batteries? yes it does... So now, instead of a 5 hr battery or whatever, you got a backup for another 5hrs. Plus all the coverage for everything else...
So, you don't need to go an actually apologize to the Best Buy salesman, but you should know more about what you speak about before you go knocking down people trying to survive in this so called " depression".
