If you travel with your baby like me and don't have enough time to shop, the best choice for one-stop shopping is, of course, Takashimaya on Orchard Road, where the luxury goods in Singapore are not cheaper than those in Hong Kong during the discount season. Health care products, Ash on the third floor is more than 400 cheaper than Beijing, and GNC health care products in B2 cosmetics supermarket are all bought one for one (the price is very cheap and tax rebate is also available, but the shelf life is approaching, so ask before buying).
