Ecrater

Very good for sellers, but be careful buyers!

eCrater is great for sellers, no fees what-so-ever. But buyers have to really check the websites sellers use in order to configure if it's a scam or real seller. Since eCrater is free and almost rule-less, it's easy for buyers to be scammed. But buyers should be more responsible and look for buyers with good reviews and a nicely put together site.
