It would be others unless you explore options like buying online (perhaps Lazada) but you only get 5% capped at RM30).

Or....can do innovative things like what I did when buying my phone.

I used my PBB VS and supplementary cards to buy gift cards at AEON big, which gave me 6% because marked as grocery. At the time it was also a promotional campaign with additional cashback 5%. So total savings 11%. I used the gift cards to buy my Galaxy S6 from Aeon Big during a promotion.

If you do the same with CIMB CR you will get 2% grocery cashback, capped at 50.
