Best Buy is running a really great (albeit a bit confusing) deal on AppleCare+ and iPad Air 2s. When you add the iPad you want to your cart with the $99 AppleCare+, it’ll automatically knock off $150. Basically, you’re getting the AppleCare+ for free and taking $50 off the iPad itself.
The benefit of buying the AppleCare+ (besides not paying for it and saving $50) is really extending your repair coverage an additional year, so you don’t have to really worry about not being covered.
