I always bid in the last 15 seconds if I want something. Like has been said above if the price goes up close to where you can just go buy it new, then why bother? I also bid what I am willing to spend in the last 10 to 15 seconds so if the person against me tries another bid and it is less than my max then I still get it.If not then I don't care because I bid my max.

I learned all I need to know about life by killing smart people and eating their brains.
