OLYMPIA, Wash. – Activists are planning a monthlong boycott of two grocery stores here after the owners said they won't stock morning-after contraceptive pills. The controversy may affect business at the two popular Thriftway stores owned by Stormans Inc., but that won't change the policy, co-owner Kevin Stormans said. "We've made our decision, and it's what we have determined. We're not going to change our position based on what happens. It's not a negotiable issue," he told The Olympian newspaper in Wednesday's editions.
