You HAVE TO list prices. People will jump all over you otherwise.
You will likely be asked to either send first, or people will complain about shipping from this far away and want you to send via a cheaper method than one that protects you. Don't.
You may encounter people trying to rip you off. There's a lot of scammers on the site.
If it's a high-end trade you could use a mod as a middle man. If selling, always use tracking.
Blowout is a great forum for daily hobby talk etc. Just beware that if you're new and trying to sell you won't likely be met with the warmest welcome. Protect yourself, ship quickly and protect the items you sell (for transit), communicate well (very important), and you should be fine.
