Yah that two cards should be okay with RM5K spending and if the BHP station where your parents pump petrol accept AMEX.

If they have high insurance premium, then look into Alliance Bank Platinum credit card too. Or can also consider Alliance Premier Debit Card where it earns the cardholder 2% cash back for any transaction.

But you also have to consider how your parents make payment and will it be a hassle for them. Furthermore are they willing to go thru the trouble to fill up the application forms and MBB got to declare liabilities also nowadays.

I can tell you this, my dad and brother in law are happy with the MBB 2 AMEX as they get to see their TP increase very fast but they had other Maybank credit cards and as such all they needed to do was go to Maybankard Cetnre at 1U to get the MBB 2 Cards by just signing on a form without going through the hassle of submitting documents.

If you can get a detail breakdown of your parent expenses, click here to read my article Earn Pocket Money with Credit Cards (if you have not). Or you can refer to my article on MACH by HLB where  I have a table.

Anyway, before you go do homework for your parent, ask them if they are willing to go apply for a new card instead of wasting your time. Older people like me can be stubborn 

Yes the Maybankard 2 AMEX cash back cap is RM50/month BUT the 5X Treats Points is unlimited. The MBB 2 AMEX earns you unlimited Treats Points Everyday for any type of transaction and on top of this it earns you cash back on Saturday and Sunday which is capped. Any by the way, if the OCBC TMC capped is reached and you need to do a transaction at a merchant where they do not accept AMEX, that is when you have the opportunity to your the MBB 2 Visa or MasterCard

If you based on cash voucher redemption, the 5X TP works out to be approximately 2.5% guaranteed returns which is better than any credit card out there.

As for MbF card, I guess if you like to gamble or into lottery, what you mentioned above is good, that is if you win it  Anyway, MbF card may be taken over by AmBank soon.
