The three tweet-activated vending machine will be located at bus stops at Oxford Street and Clapham Junction in London until 11 September. Each one will give away 260 packets a day, with the machines topped up before 11.30am and 5pm each day.
Walkers brand ambassador Gary Lineker will appear to be sitting inside the machine, responding to tweets and vending the different flavours. Visitors will simply have to tweet @walkers_busstop and a code to get their hands on the free packets.
Launched in January, the “do us a flavour” campaign asked the public to suggest a new flavour of crisps for the chance to win £1m. The final six flavours are:
- Sizzling steak fajita
- Chip shop chicken curry
- Pulled pork in a sticky BBQ sauce
- Ranch raccoon
- Cheesy beans on toast
- Hot dog with tomato ketchup
The public can vote for their favourite, with the winner crowned the “Flavour Millionaire”.
Lee-Teng, marketing managing at Walkers, says: “The Twitter vending machine is something completely new for Walkers and we are keen to make this a real must see for the public. The Do Us A Flavour campaign has taken the nation by storm so we are delighted to offer the public the chance to try the new flavours through the first ever-interactive Twitter vending machine.”
