Should I Buy A Mac From J&R Instead of Apple?
Yes, J&R is an Authorized Apple Reseller. So you get the exact same Apple warranty as if you had made your purchase at the Apple Store or Apple Store Online. And you can still go to the Apple Store for classes or Genius Bar tech support, even if you didn't make your purchase directly from the Apple Store. The advantage of shopping at J&R is excellent customer service, prompt (and usually free) shipping, and prices that are just about always lower than the Apple Store. So the only real difference between buying at the Apple Store and J&R is that J&R will save you a significant amount of money.
