Singapore Expats

I haven't seen that much trolleys in Singapore. Is it very difficult to find a twin trolley there or should I bring my own with me? What is the app. price for one?

Thanks in advance,
mom from North, with two small children

try Mothercare stores. or search through the website. it depends on the quality of the trolley, normal ones can be as low as $150 to more better ones of $700.
