Wow, that's a lot of money, but if it's your only way to get out, guess you have to pay it.. PCR tests in Sint Maarten are readily available, at around $125 and antigen tests (which I realize aren't acceptable to the USVI) are $60-$70. Surprised the USVI isn't accepting antigen tests, as, as far as I know, they are still acceptable to enter the continental US.
