Coca-Cola Great Britain has launched a mobile voucher scheme allowing consumers to sample bottles of Fanta, Sprite or Dr Pepper.

The scheme, provided by PayPoint and i-movo, lets consumers visiting any of the planned 10,000 participating retailers exchange a text message for a free 500ml bottle of any of the three drinks.

Each participant may request up to five vouchers, but only one per day, for the four-week duration of the promotion, the group said this week.

Zoe Howorth, of Coca-Cola GB, said: "PayPoint and i-movo create a national marketing network that allows us to activate promotions in the impulse channel across both independent and branded retailers. As each i-movo voucher is validated online, this offers us complete security and allows us to measure the results in real-time.

"Encouraging consumers to try these three products free of charge is an important first step in creating a long-term relationship with them."

i-movo is a secure digital voucher system using existing PayPoint payment technology deployed across a wide range of retailers and used daily by many brands.
