I have posbank (under dbs) but the svc sux, so I dun bother even
if they give me free forever. (also no bonus point system, altho'
not so impt). If they make a mistake on your statement, you can
call them and hold onto the phone for 1.5 hrs and still get no
reply...i actually tested it until I gave up. 
Now I use mostly Maybank's e-card, which is totally free, as long
as you make at least 1 transaction in 3 mths or something (very
easy to fulfill). E-card means they cut costs by not mailing you
the bank statement, but u just need to login to view your monthly
statement online. What I like is the svc is good, they always pick
up my phone calls quite soon.
