I have found AFerry very useful in the past for comparing and purchasing tickets for ferry crossings. Today having booked 2 ferry crossings I went, out of interest, to the site of the company involved and found the same crossings were cheaper. Additionally the Aferry charge for a credit card is high and the charge for a debit card is ridiculous. So use the AFerrysite for getting information but check the site of the company you are going to use and buy there.
