Jen Graham, known online as Charity Shop Girl, has built one of the most recognisable voices in charity retail. From viral social media content to appearances on This Morning and her role as an expert on the BBC's Shift the Thrift with Joanna Page, Jen is shining a light on the sector on a national scale. In this second part of our conversation, Jen talks to us about what actually drives people through charity shop doors, why social media is one of the most powerful and underused tools in the sector, and how mainstream visibility is changing the way people think about shopping secondhand.
