Sad...

pls keep it up. do not take credit card.
and, my 15% starcard, i never use for few mths already coz i pump in msia.
u want? then i let u use but u got to pay me cash based on the 15% discount, may be charge u 1% will do, meaning you got 14% discount oni, i earn 1%, still cheap right? haha...
but scare not convenient lah coz i stay at west. i can request up to $500 limit per mth i thk.
regards.
