I accidentally bought the 2014 one instead of the 2015 one. I'd like to trade it for the 2015 one. But I'll also trade for Experimental Oil Tonic, Experimental Horn, or 250 CSC.
I've got the collection for you here. Could we trade for 250 csc please?

I think I might be misunderstanding what you're asking. I'm only looking to swap my collection. I can't afford to buy one. So, are you asking to trade yours for CSC? Because if that's the case I don't have any CSC. I apologize for any misunderstanding.
