Could I suggest everyone checks their public facing Bdc page for correct pricing... I have just discovered that - for as yet unexplained reasons - Booking.com have apparently started discounting some of my rooms by 8% through to the end of August.
Not something I asked for or approved and it is causing me problems with parity with other OTA's.
My tariff on the Extranet is correct, the 8% discount is appearing only on the public facing pages!!
Check in case this is happening to you... and I think I may have to add this as a new monthly exercise from now on!
