A player who starts cooperation has a fixed price for coaching for a minimum of 12 months. In practice (for several years) the price has not been raised during cooperation (even during several years of cooperation with a competitor).
Why? Making a decision to cooperate with a trainer is a long-term action, the best effects of which can be seen after a minimum of 4-6 months. It cannot be interrupted by a sudden change in the price of the service.
*) the price guarantee for the promotional price is 3 months. After this period, the regular price is valid.
