...how much real money I spent, as in how many thousand dollars? I mean in over 13 years of Subeta? Is there a way/place/link that shows that? Thanks.

There are the Purchase Logs, but unfortunately they're not organized in such a way that you can immediately tell how much CSC you bought with real money and how much you acquired through the site.

Thanks! Can't say I understand them much, but it helps, thanks :)
