In my case 33% extra on top for 3 years coverage. Or approx a YT premium subscription.
Got the entire thing replaced in that time due to issues plus lots of micro fixes. Pays off when you get a lemon!
Having someone come to you is huge. Sending a laptop back for 6 weeks because of default warranty is a PITA and you need to source another laptop and then get it set up. As well as backup data, delete, restore etc.
For an apples to Apples comparison you should add AppleCare, since the accidental damage cover is in the price I mentioned.
