Action, which is owned by British private equity firm 3i and operates in 10 countries, opened 280 new stores last year to take its total to 2,200.

"Customers are looking more at prices because their purchasing power is under pressure. So we're seeing more customers and more transactions, and they are coming to us more often," a company spokesperson said.

Action sells name-brand toothpastes, shampoos and detergents at reduced prices, along with cheap imported household goods.
