So, a can of Red Bull doesn't give you wings after all. The energy drink giant has agreed to pay $13 million to settle a lawsuit in the US over false advertising.

The drinks maker is refunding customers who were allegedly deceived by a marketing slogan that said “Red Bull gives you wings.”

The Austrian company admitted no wrongdoing, but said it would give a $10 refund or $15 worth of products to US customers who purchased Red Bull between January 1st 2002 and October 3rd 2014.

The total amount will be capped at $13 million (€10 million), but people cannot receive their cash or voucher until after May when a court will decide whether to approve the settlement.

A website - energydrinksettlement.com - set up by Red Bull to process refunds to US customers, crashed under large volumes of traffic this week. No proof of purchase is necessary, but there's a deadline of March 2015 to submit an application.
