After watching the Domino$$s video:

Most of the ingredients needed for pizza could be acquired from local suppliers located in close proximity to the Domino$$s stores in a given city, eliminating the extensive supply chain network that Domino$$s utilizes with their hub$-$and$-$spoke approach.

What are the likely reasons that Domino$$s chooses to employ the supply chain strategy described in the video? Is it the best? Why or why not?
