Supermarkets are at snow buttle stations.

I felt very surprise when I saw  a void on the shelves in my local supermarket. The cause of this was the weather. 

For last two days there was a snowstorm in England. Many drivers spent night on the motorways in their cubs. So in the morning retailers didn't recieve their orders (products) in time. However, stores faced a "punic buying". Consumtion of first-need products (like food, for instance)  has increased roughly. 

Stores have faced problems with delivery. A lot of vans were blocked on motorways in snow captured. Christopher Sturman, chief executive of the federation which represents 45 storage companies and 16 distribution companies, said members were worried about the level of gritting of roads. He described the weather conditions as the worst for 20 years and said one of the key problems was drivers being able to get to work. 

There were also problems with home delivery. As people decided to stay at home, demand for online delivery has increased roughly. 

Analysing this event, some scientists have started a discucion about consumer psychology. Paul Buckley, a lecturer  at the University of Wales Institute, said that "social influence theory" meant that some shoppers followed the crowd  if they saw their friends and neighbours stocking up with food now.
