So, I was always wondering if I could calculate exactly how much my credit card will charge me if I were to make a transaction in another currency. I actually found out how. You have to go to your credit card type company (Visa, Mastercard, American Express etc) and find out what the rate is for the day.
Here's the link to Visa's exchange rate calculator that will give you the exact rate you will be paying. For Singapore, I only tried with DBS cards and the bank fee is 0%. Do give this a try and you might find it easier to see which site regardless of country has a better deal for your purchase.
