This one I just tried M2C AMEX since someone just posted that AMEX rate these few days might be lower than Visa/Mastercard. The AMEX rate at 0% above is just assuming that 2.5% AMEX charge applies for my transaction.
Now compare if I use MBB Visa Debit/Visa Credit.
Visa Exchange rate @ 0 % at 19/02/2018 (posting date) GBP 1 = 5.537834
If I pay via MBB Visa Debit, I would pay RM 134.57 (1.25%), 1 GBP = RM 5.60708
If I pay via MBB Visa Credit, I would pay RM 135.90 (2.25%), 1 GBP = RM 5.6625
Definitely I would pay less if I pay using MBB Visa Debit, but since this transaction is on weekends, might as well use M2C Amex. And looks like AMEX have low FX rate based on this case.
