Walkers crisps

Walkers said it had a minor code issue on 17 September

Walkers’ latest on-pack promo - which invites shoppers to take part in Gary’s Great Ingredient Hunt 2- has left some punters feeling lost.

Consumers have complained codes printed inside special packs do not work - making it impossible to take part in the promotion.

Walkers this week admitted there were problems with the system for half a day last month, adding that further problems were probably down to user error. “It’s normal for a large-scale promotion to get a certain number of issues with consumers not entering the numbers correctly,” said a spokesman. “We keep an eye on invalid codes and the number of issues is lower than historic promotions.”
