Single biggest charge to a credit card in the history

In 2009, Josh Muszynski of New Hampshire made the single biggest charge to a credit card in the history of the world. How much? $23,148,855,308,184,500 (let's just say $23 quadrillion). What did he buy? A pack of cigarettes at a BP station. The charge was the result of a computer glitch by Visa, which took the charge off his account. They also refunded his $15 overdraft fee.
