The festive season just got a little sweeter, as Cadbury is coming to Hay Hill this Sunday, December 15 from 11am to 6pm for the final stop on their UK tour.

The postal service lets you choose from a 100-120g bar of original dairy milk, whole nut, caramel, fruit and nut or Oreo to send anonymously as a Secret Santa gift to someone of your choice.

From a colleague to cousin, the chocolate treat can be posted anywhere around the UK and, after choosing their favourite flavour, you will just need to put it in one of the special envelopes, write on the address and put it in the purple on-site post box.
