Some Bloomsburg business owners are hoping the start of a new promotion will entice some new shoppers to head downtown. Participating businesses will give away $20 gift certificates to random customers every Monday through Friday for the rest of this year. More than two dozen businesses are involved. The promotion was made possible by a $5,000 donation from the Duane and Susan Greenly Foundation to Downtown Bloomsburg Inc. The promotion runs through the end of this year and no purchase is necessary.
