若果想換坡紙, 應該喺香港換,定係去到新加坡換會比較抵啲呢?

That depends on how much you want to change and how long will you be in Singapore, if it is only a small amount of money the difference will not be that big. If you only go there for 3 to 4 days. Why you need to spend time looking for money changes in Singapore and have to check the price from those shop to shop.

Frankly speaking change money in Singapore is slightly cheaper than changing money in here HK

其實這個問題都好多人問過，但我個人認為如果係旅遊性質兌換既話，係香港兌換會少私麻煩，而且HSBC現在兌換坡紙係唔收手續費（有戶口者），況且個匯率相差無幾，我覺得換定先會好的，我每次去新加坡旅行都係換定先去．

Get some changes in HK for emergency. Then go to china town's exchange outlets to check on the rates since the exchange rates fluctuate from time to time - drastic fluctuations even occur within a day... this is the experience from my days in SG - I lived and worked in SG before...
