The whole lot more is sometimes the problem. Pricenomics does one thing well.

On your site, the main call to action is to post something I've bought. Why would I want to do that? I also couldn't actually figure out how to search for an item (I entered "Macbook Pro" into the filter but didn't find what I was looking for.)

Thank you for your valuable feedback, the search is actually at the top right corner, which I thought is the web convention, but will make it more prominent now. And you are right that the full-text search requires more tweaking.
