I assume you are talking about OCBC TI ... you didn't even mention what cc are you talking about in your excitement to ask the questions.

The baseline information that you need to understand is that it all depends on what MCC does the merchant uses and this shall determine the merchant type. No one here could provide a detailed MCC list because this is strictly known only to the banks. Most guys here have shared based on their retail/spending experience, you can't get all the MCC answers OK?

a) Name also Kedai Ubat. Although it sells groceries but it is still classified as Kedai Ubat (perhaps not even pharmacy. (eg. Would you classify a clinic to be a pharmacy because they are selling medicines ? No ... you don't right ... they are still classified as a clinic)
b) All hypermarkets should share the same MCC classification. However, there was a report that 1 hypermarket is not getting the correct rebate due to incorrect MCC used by the hypermarket. (No ... we users can't do much to change this error except report to the hypermarket management)
c) Not sure.
d) I'd advise to try to do the BT and see what happens. You may put a qualifier as part of the application to cancel your BT application if the promo does not apply to you. Don't blame CS, they don't work in that department + the problem of the correct information not properly disseminated happens everywhere to banks in Malaysia. (Even foreign ones)

2) SCB Business Platinum Visa(ONLY for overseas use & purchase airline ticket as i frequently travel overseas)
    - Enjoy unlimited 0.5% cash back on all retail transaction (except petrol).    - Enjoy 3x choice points for all overseas purchases (point valid for 3 years only)
    - FREE travel insurance coverage for Principal & Immediate Family (save travel insurance fees from AirAsia when travel with family)
    - Annual fees is RM300 (make sure must call up to ask for waiver)
    - FREE Unlimited Access to KLIA Premium Plaza Lounge

perhaps MPH, KFC 10%, GIANT/TESCO (RM50 capping each merchant each month)

1,000 ESSO points = RM15 fuel actually, equivalent to additional 1.5% cash back. Every RM1 spent at ESSO will give you x1 ESSO reward point.

Very Secure !!!!
You do have alot of bills to pay ?

I think that's a good secure method.... albeit more troublesome. At least you know your account is being hacked ;-)

All the three Singaporean banks offer this kind of security device to their customers in Singapore. I think there was an article saying that this kind of security device is the most secure one. Only two banks in Malaysia offer this kind of security device while all other banks send the one time password through sms most likely due to the high cost of offering this kind of security device.

Yes, for selected merchants only. Need to think twice before deciding where to shop   
All in all, use Citi only at places where CIMB/DA do not give 5% rebate.

eh? i did that. no problem. tmpoint kajang. paid using cc for tm streamyx combo under 3 different names. but i do bring the paper bill (not just give the account num). the cashier not even ask who are the bill owner

if, cashier dont know that DA is under CIMB, show the back of the card - below the signature, got word "CIMB" there 

wow you are really a high spender.

It's been confirmed that the rebates are based on statement date ie. new card starting Sep 15 2010 - Oct 14 2010 -> only RM120 rebate and not RM240.

For the Dec period it is currently open to guesses. The rebate can be

1) RM120
2) RM50
3) tx in Dec evaluate based RM120 criteria, tx in Jan evaluated based on RM50 criteria

Most likely need to call in and ask after your statement date.

Well i got good news. Just got off the phone with OCBC CS and according to them, transactions from Dec X to Jan X (according to statement date) is entitled to RM120 rebate.

RM50 rebate for 1%+5% to start from Jan X to Feb X statements.

Disclaimer: Of course knowing the flip flops of CS, there is always a risk that the information is not accurate
