ion drugs that just went generic: Actos for diabetes, Lexapro for depression, Singulair for asthma, Plavix for blood thinning, and Lipitor for high cholesterol.
What they found was a $749 difference -- that's 447% -- between the $916 price tag at CVS (CVS 0.00%) and the $167 that Costco charged for the same five drugs. For generic Lipitor alone CVS charged $150 to Costco's $17. The generic Lexapro found at CVS for $126 could be had at Costco for $7.
Why such a big difference? Because CVS, Rite Aid (RAD 0.00%) and Walgreen (WAG 0.00%) draw most of their profits from the pharmacy, while Costco, Sam's Club and other discount stores consider their pharmacies throw-ins that help bulk up foot traffic."
From reading the reviews - it looks like you don't have to have a membership at Costco to get meds.
