I prefer Figari to Calvi. This summer fuel was cheaper than Calvi. If you don't have a total card a chap will come along and put a code into the machine. You can pay landing fees (10 euro < 2tons) in a little hut when you pay for the fuel. No need to go to the terminal.
At Calvi you need to call the fuel browser, need transport to and from the terminal, have to go through security. Fuel and taxes were more expensive.
