Final answer:
The term used when a store meets a competitor's advertised price is Price matching. This is a common practice to stay competitive and should not be confused with predatory pricing or collusion, which are different economic concepts.
Step-by-step explanation:
The term used when a store meets a competitor's advertised price is Price matching. This practice allows a store to stay competitive by offering consumers the same price as they would find with a competitor, thereby hoping to retain their business. It is distinct from practices such as predatory pricing, which involves setting prices extremely low to drive out competitors, and collusion, where firms conspire to keep prices high. Price matching is typically a sign of healthy market competition.
