About this data (2 notes)
Preliminary: this report keeps updating until the end of the report date (UTC), as more stores are checked.
Each store reports its own stock. We check every store about once a day. If we can’t check again in time, the item shows as unknown, not in stock. We read the store’s own system. No one looks at the shelf, so an item can sell out after we check.

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
Show
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 verified them against each store’s own records at the time shown (not an in-person shelf count). A store’s own system can occasionally be wrong or delayed.
