Puntarenas.com launched a new classified site – https://www.puntarenas.com/listings/, and its hard to emerge into the market but with some time and efford its worth while, so keep it up. This project is in any position to kill of Craigslist any time soon, but have interesting features and contribute to the overall discussion of what a costarican classified ad site should be all about.
This site which is also based in Puntarenas, hasn’t really launched yet (there are no listings). But the functionality is there and I like aspects of it. Puntarenas.com Ads is focused on local but accept international postings.
Some actual content would be nice, of course. But You should be patient with new services, because was launched on January 5, 2008. The site allows publish free classified listings and has RSS feeds for all searches.
