How much is the application fee for cru?

Excuse me, could you please clarify what exactly "cru" refers to in this context? Is it a specific financial service, a cryptocurrency, or perhaps an abbreviation for a larger institution? With that information in mind, I'd like to ask: How much does the application fee typically cost for the service/product/institution known as "cru"? Is this fee subject to change based on any particular factors, such as the applicant's location, credit score, or the type of service being requested? Lastly, is there a way to potentially reduce or waive this fee in certain circumstances?
