Jesus fucking god why no please stop how.
Haha, yeah, the guys who spend hundreds, if not thousands, of dollars on Steam trading cards are always interesting to take a look at.
I'd be interested to see how often it pays off for them. I got kind of into the last thing like this (what that last xmas?) and probably spent $10 or so on cards. Maybe a little more. I got a lucky Dota2 drop (from the cards) that I just sold for $38 though so that worked out all right for me in the end.
