More warehouse club maps
Locations come from All the Places, which collects them from each chain's public store locator (data from September 2026). Counts can be a little off: new stores open, old ones close, and a few locations may be missing. Population figures are Census Bureau estimates for 2024. Guess the Chain is not affiliated with Costco.
