Costco.com offers a tool that lets customers find the nearest locations by entering a ZIP code, address or city name. Customers can filter results by warehouses that have gas stations, pharmacies, optical and hearing centers, food courts and tire centers.
Customers can also choose how many locations appear in the search results. The website lists the normal operating hours of each warehouse and the hours of operation for the business center. Costco closes on certain holidays, including New Year's Day, Easter, Memorial Day, Independence Day and Christmas, as of 2015. Customers can also view locations that the company plans on opening in the near future.
