While the thriftiness is commendable, time is money, and that's a lot of time involved. Not saying don't be frugal, but I would advise that everyone assess their time investment as cost.

I grew up with super frugal parents who were perpetually poor. I copied their example for years, and I struggled to survive but made the most of it. Then one day I realized the point of "time is money." I began to evaluate the things I did to save money as a time cost. It flipped a lot of the frugality on it's head, and now I am better off than I ever could have imagined being. Because I'm no longer over investing large blocks of time to save a small amount of money.

My formula is pretty simple: if I were at work, would I make more money in the time invested than I am saving? If so, skip it.

Not saying that's for everyone or that we shouldn't be frugal. I'm still a cheap bastard. Lol But I have met many people, especially those influenced by Depression era thinking, who burn up their days to save a buck instead of going out and making more. Be wise in your time investment.
