On the Freakonomics blog, Stephen Dubner (co-author of the wonderful Freakonomics: A Rogue Economist Explores the Hidden Side of Everything) digs into the pricing on generic drugs and finds that the main-street pharmacies mark up their offerings by 975 percent!
Even once you factor in the cost of buying a membership at Costco and Sam’s Club, the price differences were astounding. Here are the prices he found at Houston stores for 90 tablets of generic Prozac:
Walgreens: $117
Eckerd: $115
CVS: $115
Sam’s Club: $15
Costco: $12
Those aren’t typos. Walgreens charges $117 for a bottle of the same pills for which Costco charges $12.
