why not?

Post #3: Rule of thumb:

PAYPAL + Amex + RM = no go
PAYPAL + Amex + foreign currency = good to go
PAYPAL + Visa/Master + RM/foreign currency = good to go

Let's say when you login to m2u and see your cc details,

Statement balance - RM 1.2k
Outstanding balance - RM 1.5k

(Outstanding balance usually more than statement balance as it combines your previous month spending with current month spending)

In that case, to avoid interest, pay RM 1.2k by the due date.
Let's say you didn't bay in full of RM1.2k (you paid RM1k), then remaining RM200 will get interest depending on the card policy.. maybe 10% or RM50 whichever amount is higher (please check as I always pay my statement balance in full  )

The RM 500 from the outstanding balance won't get charged for interest until it appears as statement balance next month.
