It saves me quite a bit of money. I never buy books until I'm sure I want to read them. When I first got my kindle, I bought more than one book at once, and I regretted it. Now I keep a backlog of sample books on my kindle. When I finish my current book, I can pick something from the many sample books I have, and if I like what i read, I buy it right then. Of course, I tend to carry my kindle quite a bit out and about when killing time (auto shop, kids swim lessons, etc)
