Let's see... I've spent in the past year:

spin dr. workstand + toolkit = $79 (very good investment... yet thinking about getting a more stable stand...)
other tools = $16 (*crap* mini toolkit, freewheel remover, hex wrenches)
Bike accessories = $115 (lights, fenders, wedge, rack, bungee)
Consumables = $135 (tires, tubes, patch kits, bar tape, cables/housing, grease, bearings, rags :B)
Clothing = $163 (rain jacket + pants, wind breaker, capris, shirts, warmers, balaclava, helmet)
Bike parts = $77 (moustache handlebars, brake levers, platform pedals)

That's about all I can think of, which brings it up to a grand total of...!!!

$585!!! OMG I'm so mad at myself! ahaha well, not really. I got seriously into commuting this past year, so... yeah. I have everything I need for all seasons, now I just gotta wait until something falls apart to buy anything that'll have any significant effect on my account balance

Oh, my dad gave me a performance gift certificate this past holiday season ($150), which I used to buy Zinn's maintenance (maintainance? wtf sp) book, polypropelene and merino thermals, neoprene gloves, and some other crap I can't remember. It was winter at the time, so I was focused on getting warm stuff to ride in :B Most of my winter thermals are packed away to rest until late fall/early winter. Maybe I should throw some mothballs in there or something...

Okay, I'm gonna go vote on this now. I had to figure out my total first before I voted :B
