program
  .command('order [item]')       
  .option('--two-day-shipping')  
  .observe()                     
  .do(command => {               
    console.log(command.args, command.options);     
    // --> { item: "JavaScript Stickers" }
    // --> { twoDayShipping: true }
  })
  .subscribe();                  

// INPUT: amazon-cli order "JavaScript Stickers" --two-day-shipping
