Marketers based in Michigan keep coming up with new ways to help the state cope with its rising unemployment rate. The latest: Grocery chain Meijer, based in Grand Rapids, says it will donate gift cards to help needy families, with each of its 189 stores providing 100 free $10 gift cards to a local food pantry. Each of the 18,900 gift cards will be accompanied by a letter from Meijer Co-Chairmen Hank and Doug Meijer. So far, the chain has raised more than $500,000 for local food pantries throughout the Midwest, and donates more than 6% of its net profit annually to a broad group of charities and organizations throughout its five-state base.Sarah Mahoney
