I thought I understood the basic rules of economics, but sometimes when I look at things in the Czech Republic I doubt it. Take for example the price of petrol.
In the UK if I want to buy cheap petrol I go to a big supplier, especially a supermarket petrol station. I would like to support one of the local independent stations, but the price differential is enormous. In the Czech Republic the reverse is often the case, better prices are to be found in the smaller outlets, so much so that it really is worth following the cheap signposts to the small independent supplier. Sometimes this is because fuel sales are a sideline to the main area of business (eg bus or lorry transport) but sometimes the reason is less obvious. How is this possible? Why does it happen? Surely the big suppliers can bulk buy fuel at a cheaper price? Answers to this conundrum welcome.
