Ah Acid,
found out.
If you take that new bus from JB and say eventual
destination is Ang Mo Kio..
Kena pwned, it's e most expensive option.
170 - Kranji - AMK: $1.01 + $0.74 = $1.75
950 - Marsiling - AMK: $1.01 + $0.69 = $1.70
CW1 (Yellow Bus) - Kranji - AMK: $0.38 (RM0.90) +
$1.57 = $1.95
AC7 - Yishun - AMK: $0.84 (RM2) + $1.15 = $1.99
So unless you're staying at Yishun, then it's worth it.
