Stores say they regularly review prices. At Drugstore.com Inc., generic simvastatin until recently had been at $125 for the common 30-tablet dose, compared with $135.99 for Zocor, even after the six-month exclusivity period ended in late December. After a reporter called to inquire about the price, drugstore.com on Friday dropped simvastatin to $27.99, which the company said was part of a regular review. Zocor now costs $139.99. On walgreens.com, simvastatin's price hadn't fallen after the six-month period's end. After a reporter inquired about it in late February, it dropped to $89.99 from $129.99. A spokeswoman said the price had already been under review.
[...] At Costco Wholesale, whose Web site yesterday listed the common dose of generic Zocor at $11.96, the company says that even at such prices, Costco is making a profit. Charles Burnett, senior vice president of pharmacy at Costco, says the company can acquire the 30-tablet, 20-milligram dose of simvastatin for $2.71. He says the price on costco.com today will fall to $10.66. Patients are allowed to use the pharmacies of clubs such as Costco and Sam's Club, even if they aren't members.
And that's the biggest lesson here: Shop around, and be sure to try the clubs. (thanks, David!)
