Costco Wholesale is a members-only warehouse offering a wide variety of products, including bulk groceries and electronics. The store is often very busy, especially during peak hours, making shopping crowded and sometimes frustrating. Customers appreciate the great food and good customer service, with some wishing for more organic options at certain locations. The store has made positive changes, such as adopting biodegradable cardboard containers for salads and reducing single-use plastics. Shoppers enjoy exploring all the aisles and recommend visiting an hour before closing to avoid crowds. Friendly staff, especially in the food court, receive high praise for their efficiency and politeness.
