Looking at advances for Plymouth - Newcastle direct on a weekday with XC, a load of the days I am looking at in both September and October are £54.45 (YP), even booking right up to most recently released dates. I know the lowest priced XC advances are normally very hard to come by in the first place, but with nearly all the ones I'm seeing being the same price, it is leading me to think that they haven't released the full quota yet (or they've been bought rather quickly).
For a sample day, have a look at Wednesday 17th Oct, both the 13.23 and 15.23 are £54.45.
