Yes, but I'm a bankruptcy attorney. I wouldn't go so far as to say I'm frugal (I have too many cycling jerseys for that), but I am a saver. Watching people on a daily basis hit rock bottom b/c they have nothing in the bank has made a big impression on me. That, and I despise credit card debt.
I may have found something to ease my conscious a bit. The Keen's I want are available at REI for a bit less than the price of Zappos. If I use my REI membership rewards, I can bring the cost down even further. Of course, Zappos has free shipping, so I have to do some math.
