When the average person runs out of money in their wallet, they hit up a local ATM and withdraw some cash. Jeff Bezos is not the average person. After shelling out $250 million in cash to buy The Washington Post in October, Bezos went to his personal billionaire ATM: his Amazon.com shares. In a Form 4 filed on Monday, the Amazon founder and CEO reported that he cashed out of exactly 1 million shares. The net gain after taxes should come to just over $270 million — enough to replenish Bezos’ piggy bank, and then some.
