Wal-Mart is the nation’s largest employer with some 1.3 million people on the payroll. And it seems there’s one of their Big Box Stores everywhere. It appears that Anheiser Busch is bailing from NASCAR’s second tier series is due to the fact that the $10 million annual sponsorship would cost them $30 million a year to stay in that series, according to published reports.
