I have noticed the 55 club promo is back again. I have tried to book on line for Sheffield to York on 6 Apl' going after 9.30 and returning after 18.00 as per the restrictions but don't get the promo fare. I think it should only be £5 return as both destinations are in one zone or have I misunderstood the rules. Are there some restrictions on which routes are available? Out of curiosity I tried Leeds to York for the same date and time and the fare came up at £5. Any help will be appreciated
