NORWALK - As gas prices continue to rise, southwestern Connecticut businesses and charities are trying to use it to their advantage by offering free gas. Some ShopRite stores are giving away $25 gas cards to anyone who buys at least $75 worth of particular items. Those include products from General Mills, Kraft and Proctor & Gamble. Store officials say it?s worked pretty well so far. The store in Norwalk gave away almost 500 cards last week.

The Courtyard Marriott hotel in Norwalk is also offering free gas cards. The American Red Cross has been giving away a $100 gas card to one blood donor every day for the past few weeks.
