The All-Clad pizza oven is on sale for $500, which is less than half the suggested retail price and hundreds of dollars lower than its usual price. This deal coincides with a big week for All-Clad, as patrons flood their parent company's site for a bonanza of factory-seconds sale. The oven comes with a rotating pizza stone that removes a lot of the fuss and bother of cooking pizza evenly, making it a game-changer for those who frequently cook pizzas. The price is unclear how long it will last, but when it does, it won't return soon.
