When the Flying Chair mounts came out, I was one of the people on Greg server who would occasionally buy the original chairs off of the vendor for 5k and sell on the mb for 30-50k. I sometimes do similar when new songs come out that you can buy for 5k; I'll buy three copies, use one, and sell the other two for profit.

It should be noted that I despise certain levels of capitalism, and am actually kinda disgusted by my own money.
