McDonald’s has launched a new promotion called Surprize Fries, where customers can win cash and other prizes by purchasing medium or large fries. From May 29 to July 2, each pack of fries will come with a peel-off sticker that reveals a potential prize. One in three stickers will uncover an instant win prize, such as £100 cash or a free McDonald’s menu item. Two in three stickers will provide a code that can be entered into the McDonald’s app for a chance to win even bigger prizes, such as £200 cash or £150 SeeTicket vouchers. To enter the Surprize Fries promotion, customers can simply download the McDonald’s app and follow the instructions. The promotion is valid at all participating McDonald’s restaurants in the UK.
