St. Louis, MO-IL metro area · July 2026 · delivery-platform prices

These are delivery-platform prices. This metro doesn't yet have enough in-store observations to publish a shelf series, so the figures below come from our separately-labeled marketplace series. Delivery listings carry platform markups, so treat the level as a delivery price — never compare it to a shelf price from another market. Month-over-month changes remain valid, because a roughly constant markup cancels out when the same item at the same store is compared to itself. Why we publish both.

Are grocery prices going up in St. Louis, MO?

The GroceryChop Price Index tracked 580 grocery delivery-platform prices across 11 stores in St. Louis, MO in July 2026, for a weighted basket cost of $4.11. A month-over-month change for this metro will publish once two consecutive months clear our minimum-sample thresholds — we withhold thin figures rather than estimate them.

How much do groceries cost in St. Louis, MO?

The weighted basket cost — the average unit price of a basket of everyday staples — was $4.11 in July 2026. This is a comparative measure, not a typical weekly grocery bill, and level comparisons between markets are indicative rather than precise because the mix of items clearing our sample thresholds differs by market. The month-over-month change is the like-for-like figure.

Where does GroceryChop's St. Louis, MO price data come from?

From 11 grocery stores across 4 banners in the St. Louis, MO-IL metro area, observed directly rather than surveyed.
