Using hashtags on Twitter for promotions is still a new area that we have written about before.  So this recent Tweet Treat campaign by Domino’s Pizza impressed us.

On offer was a great reason for followers to take part: cheaper pizza!

The promotion, which ran from 0900 to 1100 on 5th March 2012, reduced the price of a Pepperoni Passion Pizza by one pence every time someone tweeted the hashtag #letsdolunch.

The price dropped from £15.99 to £7.74, and Domino’s kept it at that price for four hours that day.

A similar campaign also took place in Ireland the same day with the hashtag #pizzalunch.  This led to a drop in the price to €13.24 from the original €20.
