(a) Notwithstanding the provisions of § 21a-79 and any regulations adopted under said section, the Commissioner of Consumer Protection may, within available appropriations, establish a program for the test audit of alternative electronic retail pricing systems that maintain and display the item and unit price of consumer commodities, as defined in subsection (a) of § 21a-79. The commissioner shall select one or more retailers to participate in any such program. A retailer participating in the program shall conduct business from one or more stores in this state. The retailer shall submit to the commissioner a written request to participate in the program and pay all costs associated with a test audit under such program. The retailer shall implement a system to be test audited that, at a minimum, (1) maintains the retailer’s current item prices and unit prices for each product in an electronic database, (2) prints shelf tags that meet all applicable requirements for item pricing and unit pricing, and (3) operates in such a way that (A) price decreases are immediately transmitted directly to the point of sale, and (B) price increases are transmitted to the point of sale only after such shelf tags are posted and such posting has been verified in the electronic database.

(b) The commissioner may designate a private auditing organization to conduct any such test audit and shall charge the cost of such test audit to the selected retailer or retailers. No such test audit shall be conducted for a period exceeding twelve months. During the test audit, such store shall be exempt from the provisions of subdivision (1) of subsection (b) of § 21a-79 and any applicable regulations adopted under said section.
