Which of the following would NOT require a pharmacy to obtain a new registration?

In the context of pharmacy operation and regulation, obtaining a new registration is typically necessary when there are significant changes that affect the pharmacy's legal status or operational framework. Changing ownership and moving to a new location both fundamentally alter the circumstances under which the pharmacy operates, which is why they require a new registration. Similarly, expanding the services offered can also involve changes that necessitate re-registration, depending on how those services impact operations, such as added regulatory requirements or changes to the scope of practice.

On the other hand, implementing a new marketing strategy does not require a new registration because it is primarily a business decision that does not affect the pharmacy's compliance with licensing laws or regulatory framework. Marketing strategies are about how services and products are presented to customers and do not alter the pharmacy’s legal structure or the services it is legally allowed to provide. Thus, this choice stands out as the only one that does not necessitate a new pharmacy registration.
