Continuing the trend of me spending far too much money on things I'm interested in (see: the rows of Xbox 360 games on my shelves):
I spent a hundred dollars on an Innistrad booster box (thirty-six packs, so $144 worth) when I got paid this past weekend. The cost is somewhat justifiable, since once the box arrives, I'm going to run a booster draft with my friends and make some of that money back.
And for more money-spending, the newest set, Dark Ascension, comes out at the beginning of February, and I plan on attending one of the prerelease events. It'll be my first time attending one of these events, and I'm pretty stoked for it, both because from what I've seen already of it, Dark Ascension is shaping up to be a pretty awesome set (just like Innistrad), and because the last time I went to a large gathering of like-minded people in real life was the Chicago Comic-Con, which I last attended a few years back, and it'll be nice to be back in my domain.
