On the face of it, I love this collaboration with Wallace and Gromit. The two brands seem perfectly aligned with each other as British icons.

The pack shows Brand Traits of Confident and Successful with Brand Values of Community and Intuition.

It’s another Willy Wonka style promotion, with a winning ticket inside the pack and other minor prizes available on entry. Note that you have to keep your receipt to enter, which is a real drawback.

The main prize is a lab-grown blue diamond worth around £1500.

The terms and conditions text is ridiculously small, to the point of complete illegibility. They may as well not exist on-pack.

To enter you have to scan a QR code which takes you to winwithbisto.co.uk. You have to enter your date of birth, name, mobile number and receipt (which I didn’t have).

The promotion ends 14 April 2025.
