I purchased a few items through Envato a while ago, including some Code Canyon WordPress themes. The quality on the backend of these has always been fair to mediocre, but the refund policy is pretty brutal, so I'd stay away from the more expensive assets if you're new to them. My main issue today is that emails from do-not-reply[at]market.envato.com cannot be stopped without leaving your email client, logging into the website, and hunting the menus looking for email notification preferences, which needs to be improved.
