From today until June 26, the US retailer will be dispensing rainbow-coloured pairs from 36 machines in both NYC and Los Angeles.
But that’s not all – to get their hands on some, shoppers must first pay with a tweet. Old Navy is willing to give away 9,000 flip-flops, essentially guaranteeing themselves 9,000 social interactions, as reported by AdAge.
The machines (as pictured above with actress Emma Roberts) will change locations each day, which fans can track on the Old Navy Twitter account and by using the hashtag #flipflophooray.
The initiative will conclude with the annual $1 flip-flop sale in-stores on Saturday, June 28.
