Zappos founder, Nick Swinmurn, has created a new website called RNKD where users can share the clothes they buy to receive discounts and rewards from retailers. The best thing about the app is that you can upload and share clothes you already have, just to prove to brands that you are a loyal shopper. The more you upload, the more points you get. You can even win a Zappos gift card. You already stunt online and to your friends about what you own, why not get free stuff out of it? [Huffington Post]
