I purshased something, then clicked the back button at the pawn shop and purchased it again :c! Is there any way I could refund it and get my 500 CSC back? Because there was something else I had intended to buy. That's like five dollars wasted.

I'm not sure whether you can be refunded or not, but this definitely something you should make a ticket about!

That's right! Tickets! Forgot about those. How do I make a Ticket?

The link is http://subeta.net/tickets.php. You can also find it under the "Subeta" dropdown menu. :)

The same thing happened to me. I really want my 500 csc back. I should probably file a ticket and close the trade with the duplicate item :/

Dude, yeah. I'm totally coming at them with a ticket xD. I honestly feel like I fell victim to a glitch, and thats really not cool considering I spent /actual/ cash this time. I'dunno. No one touches ma' money, y'know? xD

As previously mentioned please file a ticket so that a UA can assist you with this type of issue.
