PCR tests in Puerto Rico

We're vaccinated and heading to BVI on a Friday. The entry requirements say we need to have a negative PCR or rapid antigen test within 5 days of entry. We'll be in Puerto Rico on Monday (5 days ahead) and are looking for a place to get the PCR or rapid antigen test. We've found Quest Diagnostics for $110, but wondered if there are other options. Any ideas? Thanks!

FYI - your first available day to test is Sunday. That is your day 5 because arrival day isn't counted.

Even easier, bring the tests from eMed.com with you and do the test in your hotel room in PR.
