What this report covers
Grocery stores only: 37 stores in 1 city with qualifying records on this date. Stores inside shopping malls are not part of daily reports, so a report covers fewer stores and cities than the site lists. Each store reports a curated assortment of commonly bought products, not its full catalog, so "lowest in-stock rates" describe the stores Aisles covers, not every store in the area.

How this report was made
Snapshot: for every store and product, the most recent retailer-reported observation retrieved by the end of the report date (UTC). Observations past their freshness window count as "status unknown".
In-stock rate: listings reported in stock or low stock, divided by listings with a reported status (in stock, low stock or out of stock). Listings whose status the retailer did not report are excluded from the rate and counted separately.
Prices: store prices as reported by the retailer, including any promotion it reported. City and chain comparisons use only current readings with a price, take the median store price per product, and compare only identical products (the same Kroger product ID, which is the item’s UPC, so package sizes match). A chain pair is shown only when 10 or more products were priced at both.
Aisles did not physically verify stock or prices. Retailer systems can be wrong or delayed.
