The bread brand introduced the snack range, which includes ChippidyDooDaa pitta chips and SnackaDoodle wholegrain snacks, in March this year.
The digital promotion, created by digital agency Breathe, is part of £1m investment in the launch, which also includes outdoor advertising, in-store activity and consumer sampling
As part of the Crunch Time game, visitors to the Warburtons’ website must answer questions about the snack range for the chance to win prizes including plasma TVs, Sony PSPs, iPods and Nintendo Wiis
Questions will be posted at 12pm and 4pm every weekday until 20 August.
Sally Stanton, Warburtons marketing manager, says: “The new ’Crunch Time’ promotion provides the ideal platform for us to engage and reward our consumers in a fun and interactive way”.
In May, Warburtons appointed a new commercial development director and appointed its marketing director Richard Hayes to the management board.
