Saw them on HuffPost and listed for free (will probably be getting their MLS package soon though).
According to their site, they have 3 packages:
* Free - Free, but you only get your home listed on their site
* Flat Fee MLS (for FL) - $79 one time (honestly haven't found a better deal than this)
* $9 MLS + Yard Signs - I'll be ordering this one (they have a closing cost of $149 but only at the end of the home close)
I've seen their house signs in my neighborhood so I'd say they're pretty reputable.
