I know I’ve pretty much beaten to death the worst-case scenario when it comes to Best Buy’s warranty extension plans; the PSP and PRP (see the linked article for the differences between the two programs).
But, Best Buy is at least working to reduce the need to store mountains of receipts. Oh, and know where the single receipt that matters is located, when your device fails. So, they’ve made a new site, productassist.com/bestbuy.
The site does a bit more than just letting you register your performance and replacement plans that you’ve bought at Best Buy, it lets you fix errors. So, if the model number or serial number isn’t listed properly… you can change it. It’s not clear if the store will actually see these changes on their end, but at least you can show that you got it right when you registered the product online with Best Buy.
Oh, and by the way, the service is not automatic. You have to go to the site each time you buy a replacement plan.
