I have a question concerning the "share of saving" fee and the beta cross london by contactless function. It appears to me that the site still charges the fee on the London Element of the fare even though Im not buying that. The overall fee was 17.2% or £6.19 on the saving of £34 which is beginning to get a bit rich for me. I have to use the contactless London feature to avoid being sold an Zone U1 ticket from Euston To St Pancras. The fee is also in excess of the maximum 15% that the information button advertises. I bought the individual tickets in the end.
