HELIUM balloons containing free sandwich vouchers could fall over Bolton today, thanks to Poundbakery.

500 orange and black balloons were let loose from Poundbakery’s head office in Sidney Street earlier this afternoon - all containing vouchers for a free butty.

Whoever finds a balloon with the ‘Go Large’ voucher attached can grab a free sandwich at their nearest Poundbakery.

The balloons could travel from 10 minutes to 15 hours before landing, so Bolton is a high contender to be a potential landing zone.

Marketing manager, Keely Palin, said “The sky is the limit with this campaign and we can’t wait to see where the balloons end up.

“We decided to do the balloon release to launch our Go Large range and are looking forward to seeing how many free sandwiches are redeemed.

“After requests from customers, especially local workmen, who really need that extra protein to get them through the day we decided to launch the new sandwich range with extra filling so are confident they’ll be a great success.”

If you’re lucky enough to find a winning balloon, Poundbakery are encouraging everyone to tweet a photo of themselves with their Poundbakery voucher to @poundbakery with the hashtag #Freelunch #golarge

For those people who aren’t lucky enough to find a balloon, the company’s new Go Large range of subs and sandwiches are available for £1.50 each featuring extra filling for those wanting a little bit more out of their meal.

There are seven sandwiches in the range including: Chicken Feast, Cheese Feast ,Mega Breakfast Sandwich, Spicy Mexican Chicken Sub, Cheese & Ham Sub, Tuna Feast and the Chicken Salad Sub.
