Canadian Rx sales in flux
Storefronts selling bargain medicines from Canada were opened to save people the trip across the border. But locally they are closing under pressure from regulators and slow business.

The budding chain of stores, Meds-4-Less, closed a Burton location in June, while a Meds-4-Less in Lapeer closed this spring. An expansion of the American Drug Club into the Flint market never materialized.

"We had customers, but it just wasn't enough to keep us going," said Michelle Lenarcic of Davison, a franchisee who ran the Burton Meds-4-Less. "There's not a need for us because we're so close to Canada."
