other people in this tered have earlier suggested raffles money changer but i never try before so no personal comment. i know seantang uses m2u transfer a lot so you can probably PM him to ask about rates & charges.

Just changed some SGD to MYR today at my usual money changer in Ipoh. Pretty low at 2.38. Interesting thing is that I'm checking Maybank2u.sg right now, and it's also 2.38 using Regionlink. This is the 3rd time this year that I've checked and found that M2U is offering a competitive rate vs money changers. There is of course the issue of the S$15 fee with M2U, but given the fact that I had to walk around with a pocketful of SGD for the past couple of days... $15 to remove the whole hassle seems worth it.

You're kidding... there are only 2 paragraphs in that page.

This?
Anyway, you are asking from MY to SG?
Most ppl in this thread dun do transfer in that direction cause most of the ppl here have excess in SGD not MYR.
Anyway, a simple search in maybank2u website could have got you the answer.
