£984,000 for six bikes! Diseconomies of scale

Tesco mistakenly paid Universal Cycles, who are owned by Sports Direct, £984,000 for six bicycles when they were meant to pay £984. They are still to get their money back with sports direct holding on to more than £120,000. This is a great example of Tesco suffering from diseconomies of scale as they have now become so big that no one noticed almost a million pounds being paid for 6 bikes until 10 days too late!
