For a lot of people, the holiday season can be a stressful time. Fortunately, research shows that saffron makes us happier. For Swedes, that is great news because saffron-buns are a Swedish Christmas tradition. 

For the 2019 year’s holiday season, we developed real-time interactive Christmas sweaters, for the 7-Elevens staff, that detect potential costumers’ well-being. The sweaters then dictated the price of the saffron-buns, based on the general level of stress and Christmas depression within its local area. 

The sweaters had built-in micro-computers that analyzed social media posts, the current local traffic situation, as well as the weather. Three components that easily influence our general holiday spirit. When it sensed that the local Christmas spirit was dropping, the Christmas sweaters activates generous offers on 7-Eleven’s saffron-buns.

The sweaters became a conversation starter online and offline. Besides earning media attention, it became an inevitable conversation starter between 7-Eleven's merchants and their customers. The sweater was a testament to the fact that 7-Eleven always strives to make life easier for its consumers through solutions that improve their everyday lives.
