All US CCs (Visa, MC, AMEX, Discover) extend warranties. I used this feature sith American Express. Its as easy to use as can be. They just refunded my original purchase amount. I've also used price protection with Discover. Also easy to use but they take a couple weeks to process the claim and mail the check (a third party processes it) Price protection is pretty unique - not too many cards have it. If you find a lower price later on an identical item they refund the difference. I used it to get black friday sales before black friday.
