When cola brand Pepsi announced its latest advertisement, it thought it had struck gold in terms of marketing technique.
In 1996, the fizzy drink company launched its Pepsi Points scheme, where customers could save drinks labels containing points and redeem them in order to win branded merchandise.
According to Metro, Pepsi fans needed to save up 125 points in order to receive a pair of sunglasses, or a cool seven million in order to win a harrier fighter jet worth $32 million (£26.3m).
