The Costco pharmacy is said to offer the some of the lowest prices on prescription medications. And the best news of all? No membership is required to cash in on the discounts. Consumer Reports highlighted the drastic differences in prices for the same medication between CVS and Costco. It was discovered that a customer was paying $150 for a Lipitor prescription at CVS and only $17 at Costco. It may be worth switching pharmacies for those low prices.
Pharmacy is one of Costco’s top-performing categories, according to the company’s Q2 2018 earnings call.

Just like Costco’s pharmacy, the company’s optical department is also available to non-members. For anyone in need of vision care, this is one of the best-performing departments, and it’s for good reason. One reporter claimed that the sole reason she footed the $60 annual membership fee was for the optical care. Not only are the optometrists highly-trained and extremely knowledgeable, the out-of-pocket cost for uninsured patients is far less than rivaling optometry centers. Optical was another top-performing category for the chain, according to its Q2 2018 earnings call.
