Why this category prices the way it does

Produce pricing swings with season and source — Aldi and Whole Foods source different supply chains, so the per-pound number on a given week can shift more than other categories.

Indianapolis grocery context

Indianapolis is solid Aldi territory — central Indiana has been a Midwestern Aldi stronghold since the 1990s. Kroger and Meijer both operate widely. Marsh Supermarkets shut down in 2017, leaving Kroger and Meijer as the dominant traditional chains. Whole Foods has limited Indy presence (mainly Carmel and Broad Ripple). Walmart+ has near-universal coverage across the metro. Midwest regional pricing (7% below US average) makes Indianapolis one of the cheapest US metros for grocery.

Instacart-Aldi is the obvious default — Aldi prices are already low, and Midwest regional adjustment cuts another 7%. Use Meijer via Instacart for items Aldi doesn't carry (specialty brands, larger household goods).
