Singapore is the home of many super-modern, high-end shopping malls but sometimes you prefer to browse $2 mugs, faux-silk robes and t-shirts instead of luxury brands. If that's the case, head to the street markets on Pagoda Street, Trengganu Street and Sago Street in Chinatown. Stalls there are open every day from 11am to 11pm and you'll find plenty of fun Singapore-themed items to bring home for friends and family.
Unlike street markets in other parts of Southeast Asia, prices are usually fixed and clearly marked although you may be able to get a deal when buying multiple things from the same seller. There are some electronics stalls as well selling camera and phone accessories like the ubiquitous selfie-stick (you laugh but they're so much fun...).
You'll find another street market that is even bigger and more local (and therefore often has better prices than the Chinatown vendors) across from the Bugis MRT (subway) station.
