woot!

woot! is an electronics dealer with a unique business strategy. At 1am EST every morning, they post one product to their homepage. Unless the product sells out (which happens frequently), it will be for sale until the next product is posted at 1am. The product is typically an electronic item--popular items include computers, cameras, keyboards, and televisions. woot! sells the item a low price, but they stock a limited number of items and sell them on a first come, first serve basis. Thousands of people simultaneously check woot! at 1am to see what the day's deal will be. If the deal is really good, the item will sell-out almost instantly, and the site will post a "sold-out" sign until the next product is posted the following morning.

Dealzmodo

Gizmodo is a blog focused on consumer electronics. Almost daily, the blog's writers use one post to publish the day's best deals. The post usually features a picture at the top depicting some of the best deals to be found in the post. Following the banner is a dense list of product names, marked-down prices, original prices, and links to the vendor offering the deal. Because the Gizmodo writers scour most (if not all) of the other popular websites that feature daily gadget deals, this daily post, dubbed "Gadget Deals of the Day," acts as an aggregator for all of the best deals on the web.
