Costco Pharmacy is a popular destination for shoppers, offering a wide range of products and services. Customers appreciate the good deals, with one reviewer highlighting the amazing prices on Doritos chips and the liquor store attached to the store. The pharmacy is generally well-received, with helpful staff and usually not too long of a wait for prescription pickup. However, some customers have experienced issues with the pharmacy's ability to keep certain medications, such as insulin, in stock. Despite this, the overall sentiment towards Costco Pharmacy is positive, with one customer expressing their love for the store and the savings they experience on gas. The business is described as bigger and better than the competition, with a wide selection of products that can make it challenging to resist the temptation to overspend.
