Sorry, no price checking here.

Trading with marked scammers is against the site rules and you will banned if you trade with the user.

I very much doubt you'll land a mark on SR or even a ban or outpost. I'd wait for the admin to reply before you do anything, just in case.

I beleive Outpost has a No refunds policy. You'll have to eplain what happened in the ticket you submitted, the admin assigned will look into it.

The premium section of http://www.tf2outpost.com/faq might help you out.

It is not against the rules to trade with sharkers. However, beware they may shark you too.
