Costco Wholesale is a members-only warehouse known for its vast selection of items including bulk groceries, electronics, and more. Customers appreciate the great value and variety of products available. Many reviews highlight a friendly atmosphere, particularly at certain branches, though some locations can feel overcrowded. While the Gilbert and Chandler stores are noted for cleanliness and good stock, there are concerns about customer traffic flow both inside and outside the stores, with incidents of shoppers blocking pathways and causing collisions with carts. Some customers express frustration over long lines, especially during peak times, and mention that other retailers have more efficient exit systems. Additionally, there is criticism regarding the company's DEI policy, which some believe could negatively impact service and profitability. Overall, while shoppers enjoy the offerings at Costco, they urge the company to address these operational issues to improve the shopping experience.
