Irn-Bru is running its biggest-ever instant-win on-pack promotion this summer, offering 100 consumers an all inclusive, week-long holiday in Tenerife.

The Bru-Jet promotion will appear from mid-July on a number of Irn-Bru skus including two-litre and 500ml PET bottles and multi-packs of nine and 18 x 330ml cans.

Unique messages will feature on the reverse of winning pack labels, with consumers phoning a dedicated number to claim their prize. Bru-Jet-themed POS includes jet-shaped ceiling hangers, A4 posters and shelf barkers.

A G Barr’s head of marketing Adrian Troy said: "Times are tough for consumers at the moment, but we’re running a promotion that will not only be fun, but will provide 100 people with an all-inclusive holiday.

"We’re also offering all our consumers 10% off a summer holiday, courtesy of Barrhead travel."
