Illinois Statutes Chapter 30. Finance § 500/25-35. Purchase of coal and postage stamps

(a) Delivery of necessary supplies. To avoid interruption or impediment of delivery of necessary supplies, commodities, and coal, State purchasing officers may approve a State agency's purchases of or contracts for supplies and commodities after April 30 of a fiscal year when delivery of the supplies and commodities is to be made after June 30 of that fiscal year and payment for which is to be made from appropriations for the next fiscal year.

(b) Postage. All postage stamps purchased from State funds must be perforated for identification purposes. A General Assembly member may furnish the U.S. Post Office with a warrant so as to allow for the creation or continuation of a bulk rate mailing fund in the name of the General Assembly member or may furnish a postage meter company or post office with a warrant so as to facilitate the purchase of a postage meter and its stamps. Any postage meter so purchased must also contain a stamp that shall state “Official State Mail”.
