DEERFIELD, Ill. — Walgreen Co. said its stores nationwide have collected more than $1million for the Haiti earthquake relief effort, only days after the retailer enabled customers to make donations.

Plans call for stores to continue taking customer donations through the end of the month, Walgreens said Thursday. The contributions are helping the American Red Cross Haiti Relief and Development Fund send assistance and aid to those affected by last week’s earthquake, according to the company.

"This incredible milestone is a true testament to the compassion and generosity of communities across the country," Walgreens president and chief executive officer Greg Wasson said in a statement. "Our customers, patients and employees continue to lend their support, thoughts and prayers."

Walgreens last week donated $100,000 to the American Red Cross in response to the quake, and the company said employee donations of $50,000 were matched by the company.

Along with monetary assistance, Walgreens has donated six semi-trailers of bottled water, medical supplies, hygiene products and nonperishable foods through the University of Miami Global Institute for Community Health and Development. The retailer added that it also contributed 20,000 bottles of water to United Airlines’ first flight to Haiti with relief workers and supplies.
