Since I had good finals scores, my mom is offering to buy me something from the Valve store (not Steam store) or ThinkGeek.
My budget is $30 to $35. If it's around $40, maybe.
Right now, I have my eyes on the Headcrab Hat, but I'm afraid I won't get enough use out of it, and I'll neglect it, having wasted 30 bucks on something else I could have bought.
Anyway, suggest things.
