Any property seized under the provisions of this chapter may, at the commissioner’s discretion and except as otherwise provided by this section, be offered by the commissioner for sale at public auction to the highest bidder after advertisement, as provided in § 12-307, or the commissioner may dispose of such property in a manner which the commissioner deems to be in the best interest of the state.

Before delivering any cigarettes so sold to the purchaser, the commissioner shall require such purchaser to affix to the packages the amount of stamps required by this chapter. The seizure and sale of any cigarettes or other property under the provisions of this section shall not relieve any person from a fine or other penalty for violation of this chapter.
