It was very hard to get basic supplies and food when all small shops were ordered to close, and only big supermarkets were kept open, and supplied by organised convoys.
This appears to be rational at first, but it only led to people all rushing to those few supermarkets the moment the convoy arrives, and them being emptied clean by first 50 something people.
It also led to wholesale bases being emptied by supermarkets, as they have the biggest buying power, and biggest truck fleets. Here, I heard that they went through more than 8 months supply of flour in just few weeks.
The situation got much better when small shops were let to open.
Both supermarkets, and wholesalers are of course very happy with that, but that left near nothing for small shops when they reopened.
