I was going to ask how people get ideas like "The $39 Experiment: Asking Random Companies for Free Stuff", but then I read the second paragraph of the site.
How This Started
I was sitting around one day, skimming through a pile of bills that I needed to pay. I looked over at a new, unopened roll of stamps that I had sitting in front of me, and I thought to myself, "$39... for a roll of stamps? Geez... You can't get much for $39 nowadays. Or can you...?"
The results have not been shocking, but mildly amusing.
