Channel Tunnel operator Eurotunnel is cutting prices in its latest bid to compete with high speed ferry operators. The latest offer is £100 return tickets for a car and passengers travelling to France until December 31. To get this price, you must travel from the UK to France after 2pm on the day of the outward journey and to return before 2pm on any subsequent day, bookable at least one day in advance. Eurotunnel is facing tough competition from ferries and high speed catamaran services on routes from Dover to northern France. The latest rival is Speedferries.com, which recently launched a low-cost catamaran service offering to carry cars between Dover and Boulogne for £50 return.
