Your shoppers can get their hands on a personalised wrapper as a new on-pack KitKat promotion has been unveiled.

Running on KitKat Chunky, two- and four-finger packs and multipacks, the promotion is giving away 1,000 packs every day from February 1 to March 29.

Consumers are encouraged to enter codes found on packs onto a website and then upload a photo, which will be printed onto a KitKat wrapper and posted to them in a gift box.

The campaign will be backed by a £1m marketing spend, which includes digital and social media activity.
