Looking for an alternative to CraigsList? SargesList is a brand new classifieds website designed especially for military communities. It launched in January 2011, so there are relatively few listings so far, but I see a lot of potential here. Plus, they're giving away an IPad for posting an advertisement and promoting it via social networking!
There are a wide variety of categories, including housing, cars, household goods, services, jobs and free stuff! Be sure to keep your eye on SargesList as it grows.
