Since opening earlier this month, the easyFoodstore has generated a lot of buzz. It is specifically targeted at poor people, a company spokesperson told The Guardian.
A few days after opening its doors, the store that sells everything for 25p had to temporarily close in order to re-stock as it had completely sold out of products.
Part of easyJet founder Sir Stelios Haji-Ioannou's range of "easy" ventures, the store sells a variety of goods (but no fresh meat, fish, fruit, or vegetables) for 25p each until the end of February. Afterwards prices are set to rise to around 50p per item. 
Haji-Ioannou, who has a net worth of $1.76 billion (£1.1 billion) said he had the idea for the store after seeing the increasing number of people using food banks in London.
“I have a feeling that there is a gap in the food retail market – a niche below some of the current budget operators such as Aldi and Lidl,” Haji-Ioannou told the Guardian.
“I hope that a commercially viable venture offering affordable food will help many people in need as well as producing a viable return for the capital employed.”
Last year, the Trussell Trust, which manages the food bank network, said that a record number of people in the UK were now using food banks and reported and that three days emergency food was handed out over one million times over the 2014-2015 financial year. This number has been consistently rising over the last 10 years, partly explaining the huge success of a 25 p food store.
