Well, knock me over with a feather. Glenn Fleishman at Macworld reported this morning that one of their readers, the oddly-named "suspiciouschicken", found out that you can get a refund on unused AppleCare+. That means that if you purchase an iPhone every year and get that 2-year AppleCare+ plan, you can get some bucks back in your wallet.
The formula used for the United States (it varies by country) is essentially "original cost pro-rated for time remaining less the value of any service used and less a cancellation fee of either $25 or 10 percent of the pro-rated remaining value, whichever is lower" (that paraphrasing comes from Macworld's post).
Let's say you bought an iPhone 6 last year and got the AppleCare+ plan for $99. After one year and no service incidents, the plan would still have $49.50 left of value. $25 is more than 10 percent of that amount ($4.95) so Apple will deduct the lesser value, bringing the total refund to $44.55. Not bad!
It's even better if you spent money on a Mac and bought an AppleCare plan. Let's say you bought a 12-inch Retina display MacBook earlier this year and decided that you wanted an iPad Pro instead. That's covered by a 36-month plan, and at this point you've only used seven months of that plan, so the plan ($249) still has $200.58 of value left. Subtract out $20.06 for the 10 percent refund fee, and you're getting $180.52 back.
How do you get your refund? Simple. Go to this page, grab the necessary documentation (AppleCare agreement number from the Proof of Coverage certificate, the serial number of the device covered by the agreement, and the original sales receipt), and then give Apple a call. Boom, you have money!
Thank you, suspiciouschicken and Glenn Fleishman for pointing out this wonderful way of getting some cash back.
