When the advertised sale of a unit has expired, how long must a dealer/salesperson honor the offer?

The correct answer is that a dealer or salesperson must honor the advertised sale of a unit for a minimum of 30 days after the offer has expired. This requirement is part of consumer protection laws and regulations that aim to ensure fair practice in advertising. By providing a minimum honor period of 30 days, consumers are given a reasonable timeframe to act upon the advertised offer, especially if they were unaware that the sale would soon expire.

This rule helps to prevent misleading advertising practices and builds trust between consumers and sellers, allowing potential buyers the chance to purchase the unit described in the advertisement even after the initial sale period has concluded. It also gives dealers a timeframe within which they can manage stock and potential customer expectations while still complying with legal standards.
