Budget Rent A Car, according to Steve Hall, has launched a blog-based, four-week, 16-city treasure hunt, called Up Your Budget, which offers a total of $160,000 in prizes. The Up Your Budget campaign, says MarketingVOX, is being promoted almost entirely through Blogads, though some keywords on Google and Yahoo were purchased as well.
