Jeff Bezos sells Amazon shares for more than $4.1 billion in four days. The founder of the e-commerce giant can save about 288 million in taxes by moving to Miami.

About six million shares each day, at an average price of $171.7 per share. Bezos told the SEC this month that he planned to sell a total of 50 million Amazon shares, valued at $8 billion, without giving any explanation of the reasons for doing so. He has started doing it and has already placed almost half of the package.
