Costco Wholesale is a members-only warehouse selling a huge variety of items, including bulk groceries, electronics, and more. It is generally well-run with a great selection and quality products. The store is typically well-stocked with everything customers need, allowing for efficient shopping with many open checkouts and self-scan options for a quick visit. The delivery service is also noted as top-notch. However, experiences with staff can vary, with some customers reporting nice and efficient service, while others have encountered rude workers. Some shoppers feel the quality is declining, citing issues like moldy produce and noticeable price increases. The store is consistently busy, especially on weekends, and while the bulk offerings provide value, the large quantities can be difficult to justify for some households. Overall, it remains a popular destination for bulk shopping with good prices, though customers advise watching their spending.
