The No. 14 Office Depot/Old Spice Chevy driven by Tony Stewart and the No. 16 3M Ford driven by Greg Biffle will both feature a special rear TV panel during this weekend’s Toyota/Save Mart 350 at Infineon Raceway (Sunday, June 20, 3 p.m. EDT, TNT) to promote the sixth annual “Official Small Business of NASCAR, Courtesy of NASCAR” sweepstakes.

This year’s sweepstakes features a competitive new twist: Two small business owners will be randomly selected as finalists in the sweepstakes, with Stewart and Biffle going head-to-head on the race track to determine their fate during AAA 400 NASCAR Sprint Cup Series™ race at Dover International Speedway in September.

The small business that appears on the highest-finishing driver’s car at Dover will be named the “Official Small Business of NASCAR, Courtesy of Office Depot.” Additionally, if Stewart or Biffle wins the Dover race, the small business featured on the winning car will take home $1 million!

To enter for a chance to win, small business owners can simply register online at www.OfficeDepotRacing.com now through July 10.

“Building a successful small business takes a lot of hard work, and it’s great to be able to reward small business owners for their dedication,” said Stewart, who is a successful entrepreneur with 13 small businesses of his own. “I would definitely encourage every small business owner to take advantage of this amazing opportunity and enter the ‘Official Small Business of NASCAR, Courtesy of Office Depot’ sweepstakes. I promise the two finalists that Greg (Biffle) and I will be ready to take care of business and battle it out at Dover on your behalf!”

Both sweepstakes finalists will receive a $10,000 small business makeover from Office Depot and a VIP race weekend experience for two during the September 24-26 NASCAR Sprint Cup Series™ race weekend at Dover International Speedway.

The “Official Small Business of NASCAR, Courtesy of Office Depot” sweepstakes also allows more small businesses a chance to win big: Every day during the promotion window, one lucky small business owner will be randomly selected to receive a $1,000 Office Depot gift card just for entering the sweepstakes
