I think what is confusing people is that yes, AppleCare+ begins the day you purchase it. However, it’s coverage ends two years after the activation of the device, at which point month to month coverage can be purchased.
Purchasing AC+ 59 days after the device purchase date isn’t gaming the system into getting 2 years and 59 days of AC+ coverage.
re: the underlined
It must be different for computers (I think you may be referencing iPhones since you say a 2-year plan).
The last two machines I purchased, I wound up getting AC+ ~55 days after the purchase date, and in both cases, when looking up the expiration of the coverage, it's listed as ~55 days later than the activation and/or purchase date of the computer. In other words, it's not getting cut short, it shows a full 3 years of AC+, plus the days I waited.
So my current machine is an '18 Mac Mini. Here's the original purchase:
I activated the machine that same day. That would suggest AC+ added anytime in the 60 days following, would give me AC+ through roughly Sept 20th of 2022.
However, this is my Mini service status:
Note that it's Nov 5th 2022. So at the end of the day, I definitely will have coverage for ~3 years and 55 or so days, even if the first ~55 wasn't technically AC+ (and just the original factory/base warranty).
FYI, we also have an iPad, it was used, originally purchased (first owner) in mid-January, maybe it wasn't activated as it was essentially in mint/unused condition, but I scored AC+ for it when I received it in March of 2020, and it's covered through March 2022. Again, that may be a different case vs. the computer example above
