Thanks vin_ann and chary !
If interest free only valid for 20 days, that mean I will still be charge for the 1.5% p.m for certain transaction cause I have not receive the bill yet, correct me if I wrong. Example my bill cycle is 25th, and 1st Jan 09 I purchase some goodie. I will still be charge for interest if the payment did not make up to 20th Jan ... not until my bill cycle ?
For some transaction with daily interest such as cash withdrawal, Im worry if the payment is 1st in 1st out, or 1st in last out ....
If 1st in last out, all the old pending payment from ages will be charge for high interest
anyone can clarify this ?
Thanks a lot

20 days interest-free for retail transactions is from statement date.
Following your example:
Statement date: 25 Dec
Purchase date: 1 Jan
Assuming new account or no carry-forward balance, 20 days interest-free is counted starting from 20 Jan. 20 days should be 9 Feb. If you fully settle before or on 9 Feb, no interest is charged. If you pay late or do not pay full, interest is charged from 1 Jan (edit: previously 25 Dec) onwards.
Let's say you pay half on 9 Feb and carry forward half. Interest is charged until full settlement before next statement date 25 Feb. If you do not fully settle on or before 25 Feb, interest is charged again on the carry forward balance (plus the interest charged from the period 1 Jan till 25 Feb). This interest (second cycle from purchase date) is charged for the period 25 Feb until 10 Mar, even if you pay full before 10 Mar.
The above cycle repeats itself until full payment.
Credit cards are first in first out, however due to the way interest is compounded, it's far better not to buy more things than your income. If you do buy more things than your income, credit card debts should be considered highest repayment priority.
