Hammond — The Greater Hammond Chamber of Commerce is encouraging the community to visit 50 participating member retail stores for gift ideas and a chance at $2,500 in prize packages during a Small Business Express shopping event, which runs through Dec. 18.

To participate, shoppers purchase a $5 event card, then visit the 50 spotlighted storefronts to have their card stamped. No in-store purchase is necessary.

Chances to win prize packages are based on the number of businesses visited. Cardholders visiting more than 25 stores will be entered to win a $500 grand prize package. Those visiting 15-plus, 10-plus and 5-plus stores will be entered to win one of two $250 packages, one of three $100 packages and one of 24 $50 prize packages, respectively.

Cards can be purchased at the chamber office at 400 N.W. Railroad Ave., Hammond, or online at hammondchamber.org. Cards purchased online can be picked up or delivered based upon quantity ordered. Stamped cards must be returned to the chamber office by 4 p.m. Monday, Dec. 18. The drawing will take place Tuesday, Dec. 19.
