Northern Foods is running a rollercoaster of on-pack promotions across the Fox's range. Consumers can find instantly redeemable two-for-one Alton Towers Resort entry vouchers in an on-pack promotion on Fox's family and kids' lines, including the Rocky brand. Also appearing on the Rocky brand is an instant-win competition on Rocky six- and nine-pack variants, which gives consumers the chance to win prizes including Flip Video Cameras.

The two-for-one ticket offer will run until the end of August. Fox's will also be running a sampling campaign at Alton Towers, handing out free biscuit packs and money-off vouchers to theme park visitors.
