Specsavers wanted to create a dynamic, globally scalable e-commerce site to sell optical products online and through mobile. They used T4 dynamic tags to separate presentation from content authoring, allowing the content team to update product catalogs and pages without involving IT. For the mobile site, Specsavers opted to reuse desktop site assets through a responsive mobile site rather than a separate native app, to save costs and support multiple devices quickly with a small team.
