Answer:
oligopoly
Explanation:
The model that best fits this industry would be an oligopoly. This is a market or industry which is dominated by a small group of very large companies/sellers. In this model, the few companies involved are in direct competition with one another and focus solely on outpricing one another in order to gain a competitive edge. Which is what Wallmart is trying to accomplish by understanding the discounts being offered by Doormart.
