Not entirely true, you *can* repair it yourself using the Apple-sanctioned Self-Repair program.
OP, if you want OEM parts, it's about $156 after return credit (see attached image below for full bundle).
Self-repair store (officially supported by Apple): https://selfservicerepair.com/en-US/order
Apple Store will charge close to the same amount out-of-warranty. Keep in mind that if you intend to do this as a self-repair, you will need to rent their equipment.
