Extending AppleCare+ Coverage
My AppleCare+ for my 2018 MBP recently expired, and because the butterfly keyboards are extremely unreliable, I am probably going to renew my coverage. However, on Apple's website regarding extending coverage, there is no mention of price. Could someone who has done this give me some information about it (pricing)? Also if you have gone through extending your coverage, what is the process like?
