Why this category prices the way it does

Dairy is the most regionally stable category — milk and eggs track USDA market reports closely, so the price gap between services is usually under 25%.

Columbus grocery context

Columbus is well-served by Kroger (its largest physical presence in any US city), Giant Eagle, Meijer, Trader Joe's, and Whole Foods. Aldi has strong Columbus coverage — central Ohio has been an Aldi expansion priority since the 2010s. Ohio State University's presence creates a large student population that drives heavy delivery adoption near campus. Midwest pricing runs 7% below US average across all four services.

Columbus is one of the cheapest US metros for grocery delivery. Default to Instacart-Aldi for almost everything — the combination of Aldi's low prices plus the Midwest regional discount produces consistently the lowest baskets in our data.
