The promotion gives customers the chance to win one of 52 designer sunglasses vouchers worth £150 when purchasing a bottle of Caribbean Twist Blue Lagoon, Strawberry Daiquiri, Pina Colada, or Mixed Mango.

The campaign runs until the end of August and is supported by social media and consumer print activity.
