I believe the word you're looking for is "frugal". I think I can count on one hand the number of hard cover books I've purchased. Why buy it for over $20 dollars when you can wait and get it for half that, or less, when it comes out in paperback? Although paperbacks are not the great deal they used to be.
IMO it's like buying a DVD when it's first released because you can't wait for it to come out as a rental. "Patience is a virtue".
And no way in heck would I pay over $5-7 for an e-book. That's why they created libraries.
