REFER A CHARLES | Costa Coffee | Costa Club

Making Costa personal

​

As a British brand and staple on the UK high street for last 50 years, Costa wanted to join in with the Coronation in a way that included members in the celebration.​​​​​

​

We leveraged Costa's most under-utilised core loyalty benefit - Refer a Friend - into a national Charles hunt, asking our whole loyalty base to refer Charleses (and those with carolus names like Charlotte, Carol and Carlos) to our loyalty scheme.
