True or False: The buyer's premium does not have to be included in any advertising for a particular auction.

The statement that the buyer's premium must be included in any advertising for a particular auction is accurate because transparency in auction practices is crucial to maintaining trust and ensuring compliance with regulations. The buyer's premium is an additional cost that the buyer must pay on top of the winning bid, and failing to disclose this information can lead to misunderstandings and dissatisfaction among bidders.

Including the buyer's premium in advertising means that potential bidders are fully aware of the total cost associated with their purchases, enabling them to make informed decisions. This practice aligns with ethical standards in the auction industry and protects both buyers and sellers.

The other options do not correctly reflect this requirement. For instance, suggesting that it might not need to be included or is conditional on certain circumstances undermines the importance of transparency in all auction advertising. The industry best practices and regulations emphasize the necessity of clear communication regarding all costs associated with an auction sale.
