Answered my own question by going through the fine print:
8. Cancellation
8.1 Single-Pay Plans
You may cancel this Plan at any time for any reason. If you decide to cancel this Plan, you may call Apple, or you may send written notice with your Plan Agreement Number to the location appropriate to your country of purchase listed in Section 11. You must send a copy of the Plan’s original proof of purchase with your notice.
Unless local law provides otherwise, cancellation refunds will be provided as follows:
(a) If you cancel within thirty (30) days of your Plan’s purchase, or receipt of this Plan, whichever occurs later, you will receive a full refund less the value of any benefits provided to you under the Plan.
(b) If you cancel more than thirty (30) days after your receipt of this Plan, you will receive a pro-rata refund of the original purchase price. The pro-rata refund is based on the percentage of unexpired Plan Term from the Plan’s date of purchase using the calculation set forth in Section 11 for your country of purchase.
