$2.2 million

From CaseyPedia

$2.2 million was the amount of money owed by Casey Serin at the peak of his success.

Expressed in Libraries of Congress terms, $2.2 million represents 448,979 wheatgrass shots at $4.90 each, or 58,047 wheatgrass shots if the inevitable overdraft charge of $33 is factored in.
