Ill. Admin. Code tit. 38 § 125.70
Any currency exchange may charge lower fees than those of the applicable maximum fee schedule after filing with the Director a schedule of the fees it proposes to use. That filing will be made in writing with the Director by email to FPR.CurrencyExchange@illinois.gov or by mail to any of the official addresses of the Illinois Department of Financial & Professional Regulation listed on https://www.idfpr.com. Upon receipt of the schedule of lower fees by the Director, the currency exchange submitting the schedule may not charge more than the fees set forth on the schedule; however, that currency exchange may revert to the maximum fee schedule upon notification to the Director in writing of its intention to do so as provided in this Section.
