The bike$-$sharing service ofo has $200$ bicycles on Vineet's college campus. He has a subscription to the service so he can simply check out a bike at one of the "boxes" painted on the concrete sidewalks on campus and return it to any box at a later time. The service encourages appropriate behavior with the bikes through a point system. Providing bikes at boxes on campus would constitute which element of the marketing mix for ofo?
