Buy a snack, get a code, collect points and win a prize. The concept behind KitKat mobile marketing campaign recently launched in the UK is pretty simple and therefore appealing. Instead of sending product wrappers as in traditional campaigns, "KitKash" allows people to text the code to a dedicated number, collecting points and acquiring the possibility to win prizes through an online auction. The technology is provided by Yoomedia. The same campaign has been running last year in Australia.
