Absolutely agree on the warranties. I've only paid for extended warranty on two machines. One was a refurb black 2007 Macbook I bought directly from Apple's website, the next was an Alienware laptop I won from a tech website in 2018 so got for free. I extended warranty on each at the last minute because they turned out to be lemons.I get people not liking the sales being locked behind the membership, but as you note the sale prices aren't the point of the membership. They're just a value-add. That said, usually paid warranty plans aren't worth it on their own.
Moral of the story: not sure, but hopefully you find out if something's got problems in time to pay for an extension, but otherwise don't bother. I should personally learn to just sell or toss anything that has been repaired anyway, because even official company techs can screw up repeatedly over months, and my lost time is worth too much. I'm guessing higher failure rates and repairability issues are why most credit cards no longer offer free warranty extensions, too.
