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%.

New York City grocery context

Manhattan apartments rarely have room for bulk shopping, which is why same-day delivery here is a category leader in adoption rate. The five boroughs price differently from each other — Aldi via Instacart serves Queens and Brooklyn but not most of Manhattan; Whole Foods orders now go through Amazon Fresh's same-day Prime delivery (broadest Manhattan footprint); Wegmans Astoria opened in 2020 and changed Northeast Queens pricing overnight. Building access is the silent variable: many NYC apartments require leaving deliveries with doormen or in lobbies, which drives more frequent, smaller orders than the national average.

For Manhattan zips, default to Amazon Fresh + Whole Foods for produce quality and Instacart-Aldi for pantry staples (delivered via Queens/Brooklyn) — splitting the basket saves about 18% versus a single all-Whole Foods order.
