Fans of Irn Bru have started stockpiling the soft drink ahead of a planned change in recipe.
Makers of the fizzy favourite are changing the formula of the product to cut the sugar content by almost half.
It is part of a sugar-reduction programme by AG Barr before the government levy on sugary drinks comes into effect in 2018.
But fans have launched the "Hands off our Irn Bru" petition, attracting more than 6,000 signatures.
Irn Bru drinkers are angry after the manufacturer revealed the new flavour would appear in stores in January.
They have been taking to social media to vent their dismay, with stories of people buying up to 250 cans mentioned but not substantiated.
