kout.io

Very interesting concept! From their about page: Kout is the fun way to checkout. You can safely play for a chance to win your favourite products - we have thousands to chose from! (they are new and coming from trusted retailers such as Amazon). At Kout, we like to do thing differently. We were sick of getting ripped off on deals or vouchers websites so decided to build one with the customer - you! - first in mind. Our aim is to deliver a seamless experience, so that whatever you want to buy - you can always try your luck on Kout first, at no risk! We have 20x more winners than the average auction site. And we intend to keep it that way! Google Chrome user? Use our extension to play directly from Amazon! If you have a site or a blog you can embed our games and make money from them!
