That got me curious. Google maps says that from London to the Apple store in Lille, France is about 4 hours by car, and the same for the return trip. Googling suggests that it would be about £120 for round trip transport through the tunnel. It says that by train it is about 90 minutes each way and would cost about the same as the car trip.
