“On March 4, 2008, Airborne Health Inc. agreed to pay $23.3 million to settle a class-action lawsuit brought against the company for false advertising. Customers with proof of purchase will be refunded for any Airborne they have ever bought. Those without proof of purchases will be reimbursed for up to 6 packages.”
