Costco Wholesale has decided to not sell the abortion pill mifepristone across all its U.S. pharmacy stores, citing low demand.

This isn't a change in policy or Costco ( COST ) dropping the medicine. It has never sold mifepristone in its warehouse clubs or through its pharmacies.

"Our position at this time not to sell mifepristone, which has not changed, is based on the lack of demand from our members and other patients, who we understand generally have the drug dispensed by their medical providers," Costco said.

The decision comes amid campaigns against the pill by religious activist groups, including Inspire Investing and Alliance Defending Freedom.
