If you have a gnarly case of tsundoku, eBook samples are a lifesaver (and takes the burden off of your pocketbook). My apartment is crowed with the unread voices of books stacked in vertical piles, lined up in horizontal leans, and boxed up tetris-style in totes. Not to mention my dust gathering digitals. Lately, nearly every time I want to impulsively buy a book, I opt for sample chapters instead. How do you manage your itchy book buying fingers?
