Shoe brand Miista has unveiled a social media campaign, created by RAAK, which allows users to give a discount to all consumers by tweeting about it.

Through the ‘cheaper with a tweet’ campaign, every time someone tweets through the shop page about a specific style from 3 to 13 January, the price will automatically decrease for everybody.

The campaign has been designed so the higher a Klout score a person has, the more the pair of shoes will be reduced by.

According to the website, an active and average Twitter user has a Klout score of about 20, so their tweet could cause the price of the shoe to automatically drop by 1.5%. If enough tweets are sent, or people with high Klout scores participate, shoes could be sold for just the £1 postage fee.
