Jim "Mattress Mack" McIngvale sold so much furniture in a week that he could afford to place another giant Super Bowl bet -- $5 million on the Cincinnati Bengals to beat the Los Angeles Rams.
McIngvale, who owns Gallery Furniture in Houston, Texas, drove across the border to Louisiana early Friday morning, pulled over at a rest stop and placed the $5 million bet on Caesars Sportsbook's mobile app at +170 odds. McIngvale is running a promotion at his store, offering to refund any purchases of $3,000 or more if the underdog Bengals win Super Bowl LVI.
