I dislike paying through cash.

If there are some reasons the seller made a mistake or the shipment is taking too long, using CC allows me the flexibility to "dispute" that transaction..

And I do not "lose" any form of cash during that procedure.

Since the experienced I had with payment at Mydin using my debit card, I strongly agree on this.

just use paypal and get confirmed 4% instead as mentioned by lilsunflower 

For quantum, yes.
