This is an example of a rack jobber.

Explanation: A rack jobber is a type of wholesaler that specializes in setting up and managing product displays on racks within retail stores, particularly supermarkets. They are responsible for delivering merchandise to the store, setting up the items on racks, and regularly restocking them. They also keep track of inventory levels and ensure that products are properly displayed to attract customers. Unlike drop shippers or truck jobbers, rack jobbers focus specifically on managing product displays on racks within retail stores, making it the most fitting answer in this case.
