Who is Target's biggest competitor?

I'm curious, who stands as the primary rival for Target in the retail space? With so many players in the market, it's intriguing to know which company consistently challenges Target's dominance, whether it's through pricing strategies, product offerings, or customer loyalty programs. Is it a well-established chain like Walmart, Amazon encroaching on traditional retail territory, or perhaps a niche player that's been able to capture a significant share of consumers' attention and spending? Understanding the dynamics of this competitive landscape is crucial for investors, consumers, and anyone interested in the retail industry.
