I live in Chiang Rai, and my USA bank gives me free ATM debit card withdrawals which I have found to be the best and simplest method for getting Bahts. I can withdraw $500 per transaction $1000 daily limit so I pull out 17,000 Baht twice and deposit in my Thai bank. Do not take the conversion option as it will cost you about $30 in what you will get without conversion.
It would be very helpful to know what the real savings would be. Where can I see the TT rate, and when does TT stand for... I used Tempus when I needed $1M switched to Euro's. So far I have only used Wise for a couple $30K moves, and many ATM withdrawals...
I bought a Catana Bali 4.8 catamaran in France 2021 and sailed it back across the Atlantic. Put in crewed charter service in the BVI. Broker told me too big to ship??? guess nothing to big to ship.
You will get a slightly better exchange rate with $50 and $100 bills than $20 (and smaller) bills. I save my smaller bills for other countries that like $$$.
