In France, buyers "lost patience" when a supermarket chain significantly lowered the price of jars with Nutella, a chocolate used to tear bread.
Homemade chocolate fans collided with each other when the "Intermarché" supermarket lowered its selling price by 70 percent.
"They were brought up as a pet. A woman pulled her out of the hair, a teenager threw a box on her head, another had her bloodied hand," a client told a French media.
Videos posted on social media showed large crowds of people catching as many jars with nutella could.
In some stores in northern France, police intervention was needed due to clashes between customers.
An employee of a store told a newspaper that he had seen a customer with a naked eye.
