Hi all - is the Apple store the only place to get a new Apple Battery? Specifically, my 15" MBP is a year old and the battery now only lasts about 30 minutes or so. The computer is past warranty and I dont have applecare (though I don't think batteries are covered anyway). I just wanted to check and see if there was any hidden treasure you all knew about for getting a 15" MBP battery. thanks!
