Just thought I'd mention this. Our friend (a British Nurse) was unlucky enough to travel on the flight from Gatwick, where everyone caught chest infections. Being a Nurse she thought she's visit the Pharmacy in Caribbean Street. Here she was able to buy Amoxylin 100mg (a wide spectrum anti-biotic), for just $US10 for the course. She took these for the 3/4 days prescribed and was fine. This saved money on Doctors fees and the Pharmacist was very professional.
