Domino’s Pizza ran a promotional social media campaign on Twitter during which they asked their followers to add the hashtag #letsdolunch to all their tweets. In return Domino’s gave huge discounts for that day lunch, reducing the price of the star pizza according to how many people tweeted in time for lunch.

The popularity of the #letsdolunch hashtag became so high that soon the number of tweets mentioning it rose to around 82,500 – a huge boost for the brand value of Domino’s Pizza. Overall a successful, one-off campaign that raised the profile of Dominos by tweeting about it!
