I have just Booked on Tuesday 1st May for May 8th, Exeter-London Victoria rtn 04.30 out, and 19.00 back for 21 rtn, over the week before I booked, I kept an eye on the prices, which started 13-15 mark both ways, then climbed to 27.00 odd for the 04.30 and then this Tuesday 1st may, went down to 11.00 for 04.30 and 10.00 for 19.00hrs, which happy to book at, seems odd way to price as at over 40.00 for return, it put me off, as with Network Card I can do Exeter-Waterloo for just over 40.00 rtn, Is reason for this very sensitive quota pricing or glitch, as went up and down very quickly, just seems weird pricing, anyone else found this the case?
