Lux Express does not offer group discounts, but there are lots of other discounts available which are related to travellers age. All available discounts are visible while purchasing a ticket. A list of all available discounts is visible here.
Also, we recommend buying your tickets as soon as possible, because Lux Express is using dynamical pricing which means the price depends on the time until departure and demand.
You can buy tickets by using Lux Express homepage or by contacting us.
