I used the Cadisco station on the way from Orient Village to the airport and the attendant said they charge 1 for 1 when paying in cash. Very nice young man, polite and helpful.
Also in Nettles Bay a Cadisco station, 1 for 1 and they are cheaper than the dutch side plus have a very good supermarket albeit in French. Found the green Pic Mosquito coils there and not the black ones they sell for $1.00. Cheap yes, but they don't work, the Pic ones do. Amazon also sell them, so taking a few with me next time.
