AppleCare discount
I made a purchase for the new iPad Pro under the education discount. Unfortunately I didn’t get the discount when I purchased Apple care for the device.
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi, Cell
Oh, okay, thanks for the update. I don't work for Apple and I can't spend my time constantly checking for every promotion Apple offers.
If you think there's an error in your billing then you need to contact Apple:
