Booked Pompey - Caen return last week with Brittany Ferries for two cars and a 4 person cabin hoping to get a good early cheap deal and paid £651(out Tue 23.15 back Sun 23.30). Checked out web prices this morning and return crossing fare had now dropped £30 per car. Made complaint call to Brittany who are now sending another invoice saving £60. Worth a check if you booked return on Sunday night last week!
