AppleCare prices are fixed and what you see is what you pay. The only way to get a discount that I am aware of is through education pricing if you are eligible, which knocks it down a little bit; $219 vs. $183.
Applecare is one of the education discounts directly from Apple that's actually worth it. You won't find it that cheap even with B&H's no tax. I'd just get it from Apple. All you need is the serial number of the device and your student ID, and I just walk in and buy it.
