Costco vs. Sam's Club: Who has better prescription drug prices?

KANSAS CITY, Mo. - You can find nearly everything you need at warehouse stores like Costco and Sam's Club, including prescriptions.

The Institute for Healthcare Informatics gave NBC Action News the top five prescribed drugs in the U.S. We then compared the cost of those drugs at Sam's Club and Costco stores in Kansas City for non-member, generic prescriptions to learn which store had the best deals.


First on the list are 30 tablets of 20 mg of the generic version of the acid reflux drug Prilosec. Sam's Club charges $35.72. That's nearly three times more than Costco's price, $12.66.


Sam's Club and Costco both charge $5.90 for 40 mg of the generic version of Zocor.


Sam's Club is slightly cheaper for the blood pressure-lowering drug Lisinopril. 60 tablets at 10 mg is $8.00 at Sam's Club. Costco is a bit higher at $8.52.


NBC Action News also compared another popular medication, amoxicillin. Costco charges non-members $5.90 for 30 500 mg capsules. But you'll get a better deal for the same medicine at Sam's Club, which charges $4.00.


When comparing the pain pill Hydrocodone, Sam's Club charges $11.68 for 30 tablets at 5/500 strength. Costco is a slightly less at $10.86.

NBC Action News also checked the price for hydrocodone at CVS, Wal-Mart and Walgreens. CVS was the cheapest at $12.19, followed by Wal-Mart at $14.08 and Walgreens at $19.99.

It's important to do some research before you spend any cash. It can be as simple as calling different pharmacies. Pharmacists we talked to gave us prices over the phone for everything we asked, with no problems. Many chains even offered to match other stores' prices.

Also keep in mind, Costco and Sam's Club offer prescription discounts to members. So that's a something to consider when deciding if a warehouse club membership is worth it for you.
