Tesco Express shops are neighbourhood convenience shops averaging , stocking mainly food with an emphasis on higher-margin products such as sweets, crisps, chocolate, biscuits, fizzy drinks and processed food (due to small shop size, and the necessity to maximise revenue per square foot) alongside everyday essentials. They are located in busy city-centre districts, small shopping precincts in residential areas, small towns and villages, and on Esso petrol station forecourts. In 2010 it became known that Tesco was operating Express pricing, charging more in their Express branches than in their regular branches. A spokesperson said that this was "because of the difference in costs of running the smaller shops".
