Time to start camping out in front of your computer. Amazon this morning kicked off Black Friday week with a landing page devoted to the consumer holiday. The page is devoted to more than just Friday, with “doorbuster-style deals now through Cyber Monday”–a full week of discounts, starting today.There are plenty of deals is just about every Amazon category–particularly in electronics (though, fair warning, that page doesn’t seem to be particularly well formatted for the Chrome browser). There are a number of on-going deals, as well as “lightning deals,” which will only be available for an extremely limited time, starting with the Creative Labs HS-980 Fatal1ty Professional Series MKII Gaming Headset, which will be discounted to some mystery price (from $99.99), later today.Available electronics categories include TVs, camers, GPS, MP3 players, laptops, storage, printers, and cell phones. All of the items on the page are eligible for Amazon’s free shipping deal on orders over $25. A quick sampling of some of the available deals, after the jump.
