What is the ruling on offers presented by sales representatives to pharmacies, such as giving additional free items when purchasing a certain quantity, and what is the ruling on the competition that drives the representative to offer more free items?

Pharmaceutical companies are permitted to reduce drug prices or provide free medicines to pharmacies as an incentive for purchase. This is considered a commendable leniency in selling. Promotional gifts are classified either as pure donations or as part of the sold item. However, a representative is not allowed to dispose of medicines through gifts or discounts without the company's permission, because he is entrusted, and his actions are restricted by authorization.
