Cadbury's secret santa

This is a fun one to look out for on your travels. From Cadburys:

This Christmas you can send a free chocolate bar, in secret, to someone special. All you have to do is find one of our Postal Service posters.

They’re popping up all over the country. Find a poster and give someone a little lift.

The digital posters can be spotted at bus stops, on high streets and even in train stations across the UK

Posters will show a QR code that people can scan and be taken to the digital postal service where they will be shown if there is a bar in stock.

If there is, they will be taken through steps to send their choccy bar secretly to someone special!
