The guarantee has a few stipulations. The item has to be posted within 50 miles of the Chicagoland area, has to be listed for at least 30 days and the guarantee can only be exercised once.

There are several start-ups trying to gain market share in the realm of online classifieds; which has thus far been dominated by Craigslist.
