In case anyone wants to know, the exchange rate at the Cambio by Valuemaster was 119/1 today at around 11 AM Negril time and at the Cambio near the HiLo Supermarket, it was 121.2/1 after a short walk to there.
To use my Visa card at the HiLo, the exchange rate was 127.50/1.
That is all I know about that.
