Budget Rent A Car, with help from blogger B.L. Ochman, today launched an online-only campaign - Up Your Budget - in which "treasure hunters" from across the country can follow online video clues, blog about their experiences, and search for a two-inch sticker which, if found, can be used to claim one of sixteen $10,000 prizes, reports MediaBuyerPlanner.

The campaign is being promoted almost entirely through Blogads, though some keywords on Google and Yahoo were purchased as well.

Here's how it works: Video clues for four new cities per week, for four weeks, can be found at the Up Your Budget site (developed by Design 4 Results). There will be a new video clue there each day of the week for each city (but the name of the city isn't shared - treasure hunters are left with only a region and must discover the city themselves).

The video clues begin at a Budget location, then move on to show a few seconds of the city. By Friday, the clues will tell a story that leads to the treasure, symbolized by a two-inch sticker in a public place.

The treasure hunter who finds a sticker must document (with video or a camera) the find, then call the 800 number on the sticker. Treasure hunters also have their own blog where they can write about their experiences and upload videos or photos of their search.

Ads are running on about 40 of the top blogs that cover the topics of lifestyle, music and baseball, among others. "The point is to prove that traditional media does take the news from us (bloggers) these days," said Ochman.

With that in mind, Budget has not even prepared a press release about the campaign.
