owlmoose | Pre-spring cleaning

My desk is out of control again, and I'm taking advantage of working a couple of nights to attack the problem. In order to make sure I have a place for everything I unearth, I'm cleaning out and organizing my filing cabinets, too. As you might expect, I've come across several archaeological discoveries, raising the usual "do I save this or not" questions.

Like, do I really need to save a receipt for a notepad purchased with cash at a local office supply store in 2004? Probably not, but you know I'm going to go ahead and file it anyway...
