(a) A licensee may not solicit business by means of a "pre-approved," "approved," or any similar expression unless the statement or offer is unconditional. The term "unconditional" means not limited in any way.(b) Subsection (a) of this section does not apply to a firm offer of credit, as that term is defined in 15 U.S.C. §1681a, that a creditor extends to a consumer following the procedures prescribed in 15 U.S.C. §1681b and §1681m.(c) A licensee may not require the purchase of any goods, services, or intangibles from any person or firm as a condition to the granting or extending of credit, except as specifically authorized by the Texas Credit Title.

This section must not be construed so as to prohibit the conduct of another business by a licensee as is authorized by Texas Finance Code, §342.560.
