SINGAPORE -- Consumers in Singapore often let out a sigh at the sight of high price tags in supermarkets, such as 4.5 Singapore dollars ($3.25) for a bag of potato chips or S$8 for a 500-milliliter can of beer, and then just walk away.
In 2015, Singapore remained the world's most expensive city to live in, topping Paris, Zurich and others, according to a British journal survey.
