so makes me want to switch to grab more, i.e., if grabpay available, then use cc to topup grabpay
grab rewards RM 10 = 1600 points, for platinum, 1600 points requires RM 1600/3 to spend
so equivalent cash back = 10/(1600/3) = 1.8%
so bye bye amex on weekdays, only worth to use it on weekends 5% cashback
It's technically the same for AmEx and Grab CC cashback.
If you spend RM100 via AmEx, 5% cb = RM5.
Reload RM100 via Grab CC and spend RM100 on GrabPay, 100x8 = 800GrabPoints = RM5 = 5%.
Of course you would need to be on Plat level on Grab then only you'll enjoy the 5% but also, it's better to use AmEx as it guarantees 5% in cash value while Grab Points, Grab can anytime devalue it.
So if you are a cashback fan:
weekday -> Grab CC and pay via GrabPay
weekend -> AmEx.
