Yes. It depends on the medium in which the client purchases the tickets. The values may vary depending on whether: Sales Web (www.bussur.com) / Presential (offices) / Assisted Sale (email@example.com) / Tourism Area / payment with Frequent Passenger Club / Specific promotions or Season.
You should consider that internet sales do not always have the same values as office. This particularly for the case of external sales via Turismo Laguna Azul, there are different values in agencies than on the internet (assisted sales).
