I logged on at 06.15 this morning (Wednesday 22nd) and although there was the day shown, there wasn't any prices displayed, so no options to book.
I had to leave at 06.30 so didn't get a deal.
Have checked tonight and the fares range from £45 - £60 each (no luggage) departing on Sat/Sun 6th/7th Oct 18, coming back on either the Weds/Thurs/Fri, prices were all about the same for the return journey (£16 each lol).
I didn't book as it's a long way off yet and the prices aren't actually that much different for me nearer the time of departure. (approx £60 - 65 each this trip just gone). Might be an idea to deffo agree on a meet up date anyway.
