CHEAPEST AT BRAS BASAH! (edit: i think they dun have much yen, maybe for a few hundred sing dollars)
Changed
Arcade(Money Exchange): most of my money at 15.25
Arcade(CIC): 15.23
Bras Basah: 15.2
At first my mum and I went around lunch hour and found that 15.24 was the lowest at the Arcade. But Hassan and a few others were so packed! Its funny why no one noticed Money Exchange (past Hassan, near to the end). They always have pretty good rates too. So we went to change at 15.25 without queueing. But they did not have enough yen. So we decided to look at the 1st floor and changed at CIC, where there was no queue again, and 15.25 was their shown rate. But funnily they gave us 15.23 so we kept quiet haha.
After my lesson, I wanted to go to the Arcade as the rates tend to drop on late weds but I saw a money changer offering 15.2 when I passed by Bras Basah. I've a feeling though that maybe Arcade is cheaper than that now.
