I have always known that Kanye West's wife, Kim Kardashian and the rest of the Kardashian girls make a killing from promoting products on their various social media platforms. There was even a time about 5 years ago when I was carrying out a research on Kim and I discovered she was making (back then) a cool $2,000 on each promo Tweet she put out there for people. But never did I ever imagine that she makes as much as $500,000 per campaign advertisement on her Instagram page.
