A purchaser of any correctional industries product or service (other than license plates) may appeal the price of the product or service to the Price Review Board at any time prior to or within 30 days of the time of sale and upon payment of the price. The board may permit the filing of an appeal prior to actual payment of the price upon a satisfactory showing by appellant that it has completed all acts necessary on its part to make payment and that payment will be made no later than 60 days after the filing of the appeal. Where the board permits such an appeal to be filed prior to actual payment, and appellant thereafter fails to make actual payment within 60 days after filing its appeal, such failure to pay shall divest the board of jurisdiction and the appeal will be dismissed. The sole grounds for bringing such appeal is that the price as established by the commissioner unreasonably exceeds the fair market price for such goods or services as defined in this Part, or that the fair market price was not established in accordance with section 186(2) of the Correction Law.
