NASCAR Sprint Cup driver Tony Stewart appears to have easily made the switch of depots this year. Stewart, who has replaced his longtime primary sponsor Home Depot with a co-primary sponsorship between Office Depot and Old Spice, visited the Boca Raton campus of the office products retailer earlier this month.

He signed autographs, posed for photos with employees and talked about what it’s like to run his own race team. And as he was getting ready to leave the stage, where he’d spoken with employees, he said, “Oh, one more thing,” and then he surprised Office Depot officials by pledging a $100,000 donation to the Office Depot Foundation.

Stewart is so popular that Office Depot, which previously sponsored Sprint Cup driver Carl Edwards, has received a number of requests for NASCAR Hero cards featuring the driver, and has sent out about 200 just in the past two weeks.

Meanwhile, Stewart is getting support from another South Florida corporation. Miami-based Burger King signed a multi-year sponsorship agreement with Stewart last week. It’s also getting the primary paint scheme on Stewart’s car for two races this season: on July 4 at Daytona International Speedway and Sept. 27 at Dover (Del.) International Speedway.

It just so happens Burger King is also an Office Depot customer.
