What type of arrangement requires a buyer to purchase additional products as a condition of a primary sale?

A tie-in arrangement is a type of sales practice where a buyer must purchase additional products or services as a condition of receiving a primary product. This can occur in various industries, including real estate, where a buyer may be required to engage in purchases or transactions beyond the main sale they are interested in.

The concept is often scrutinized because it can restrict consumer freedom and competition, and practices that constitute illegal tie-in arrangements can be challenged under antitrust laws. In the context of real estate, this could mean requiring a buyer to commit to a specific mortgage lender or to purchase related services like home inspections or warranties in order to complete a property transaction.

Understanding this arrangement is important for recognizing potential ethical issues in sales practices. The other concepts listed do not accurately describe this kind of mandatory purchasing situation in relation to a primary sale.
