Light humor - Where do you draw the line on being cheap?

At Wallet Pop, I ran into this interesting piece on where to draw the line on being cheap. I must confess, I have seen some washable feminine hygiene products out there on the net... but even I may be too cheap to go there! Some are pretty grotesque... though I did just pass some roadkill not 10 minutes ago. I remember my mom taking out a nice buck in deer season. The police came and a guy stopped. He asked if he could tag the deer and have him. The cop didn't seem to mind and neither did my mom.
