Why this category prices the way it does

Frozen pricing is dominated by Walmart and Aldi's vertical integration — Amazon Fresh's frozen selection is limited and tends to run higher per unit.

San Diego grocery context

San Diego's grocery scene leans heavily on Vons and Ralphs (both Kroger), with Sprouts as the primary organic-and-natural option. Whole Foods has a smaller SD footprint than LA. Aldi opened its first San Diego stores in 2022-2023 (Chula Vista, El Cajon) and delivery coverage is still expanding. The Mexican border proximity means many SD shoppers cross-shop in Tijuana for produce — a habit that delivery services have eroded but not eliminated.

Without strong Aldi coverage, Walmart+ becomes the default cheapest option for most San Diego zips. Sprouts via Instacart is the best produce-and-natural-foods alternative to Whole Foods at noticeably lower prices.
