If you hv Ringgit msia want to change Rp. Maybe can consider change to S$ then to Rp.
This was my experience yesterday.
At Bjy the rate was
Rp1J/Rm320 and
S$1/Rm3.10
For illustrations...
I paid Rm310 for S$100 at JB.
As all Bros should know...
now in btm S$100 can get > Rp1J++
I also save > Rm10 (320-310) on top of the extra ++.
I got 10070 at Btmctr(XE was 10087)
And
I used Rm10 less to get S $100
Total I save about S$3.70 per Rp1J.
