First thing this morning, I went to the ATM in Chonburi Thailand and made a withdrawal of 20,000-baht, plus the 180-baht fee (for all ATM in Thailand), for a total of 20,180-baht. 20,180 divided by 614.93 shows that I received a currency conversion rate of 32.76 baht/USD.
Today’s best exchange rate (that I forgot to take a picture of) was 32.70 baht/USD.
After making my withdrawal, I logged in to the Bell Bus site to purchase a ticket to the airport. As usual, they try to make me accept the “convenience” of online dynamic currency conversion. The rate today was 32.70. Had I taken their “kind offer”, I would have earned a much lower rate of 31.12!
So after declining DCC, I paid $7.03USD instead of $7.39USD. I realize that when you look at it in these small numbers, you wonder why it is important. But it adds up when 90% of your monthly spend is by credit card or ATM purchases.
