Better Business Bureau warns of fake grocery, gas vouchers that could cost customers

CHICAGO (WLS) -- Got a postcard promising hundreds of dollars in free gas and grocery vouchers? The Better Business Bureau says stop before you pay a fee to "cash in."

Never pay upfront for a prize or reward. Research the offer independently, and never give payment information under pressure.
