Many items on Amazon come from third-party sellers on the Marketplace, indicated by a "Sold by" line near the "Add to Cart" button. If both Amazon and third-party sellers offer the item, the large "Add to Cart" button buys from Amazon, and you'll see a few alternative "Add to Cart" buttons with different prices and a link to a full list of used and new versions of the product. Marketplace sellers set their own prices, so you might find a great discount on a used item, or come across a rare, discontinued product that's only for sale at a collector's price. Even when buying from another seller, Amazon itself handles your payment, so you don't need to worry about your credit card information leaking out.
Although As Seen On TV was founded in the 1980’s by Shark Tank panel member Kevin Harrington, the public domain label is often used to refer to all infomercials that have aired to date – ranging from the familiar Ron Popeil and his line of popular “o-matic” products, to Sir James Dyson and everyone in between. The infomercials all use direct marketing which allows customers to immediately understand the benefits of a product, and provides the seller with an easy way to track results and understand if a campaign will be profitable.
