Prior to getting my ereaders, I had not purchased a novel in more than 10 years. My public library had a great selection of current novels, and I picked up most of my reading from the new arrivals shelf. If I wanted a book they didn't have, I had them get it for me via interlibrary loan, and they were able to get absolutely any book for me, often from several states away. I didn't want to buy books, not so much for the price, but for the clutter.
Since getting my ereaders, I am rather appalled to say that I have purchased hundreds of novels. A large number of those come from the "other customers who bought this also bought these," where I start by looking up one book and finding 6 more that interest me. It's not traditional browsing, but it is browsing nevertheless. I doubt I am the only one who gets caught up by the ease of shopping on Amazon.
