Executive members pay $130 a year for their wholesale club membership. Gold star members pay $65 a year. Last Autumn, the wholesaler installed membership scanning devices at the entrance of its warehouses. A new Costco is also in the works for Miami-Dade County.

Shoppers with executive memberships will be able to earn earlier access to Costco locations, with stores opening at 9 a.m. each day exclusively for executive members. Currently, Costco locations open to all shoppers at 10 a.m.
