How much does it cost to join JITO?

Could you please enlighten me on the matter of JITO membership fees? I'm curious to know, what is the standard cost associated with becoming a member of JITO? Is there a one-time fee or are there annual dues that need to be paid? Also, does the membership cost vary based on any specific criteria, such as the type of membership or the benefits it offers? I'm eager to understand the financial implications of joining JITO and would greatly appreciate it if you could provide a detailed breakdown of the costs involved.
