I haven't come across any agent in Bangkok that is 28 to 32k , I have been in contact with 3 and lowest was 39k single entry and highest 55k . I need multiple entry as I need to go to the UK every 4 to 6 months to see my grandchildren
I am doing the same. Just extended my first 60 day last week and off to Phu Quoc for a week at the the end of this month . My flight back to the UK after I come back from phu Quoc is already booked and paid for. I will then return to Thailand to retire in December
