What controls price in a market with pure competition?

Supply controls price in a market with pure competition.

Explanation:

Demand ordinarily was meant to be the factor that controls price, but in a competitive market, demand shifts as availability increases. Consumers tend to consume a more available product than a product that is rarely available. So, if market supply supersedes the competitor's supply, then the price of the product can be controlled.
