I pretty much stopped going to new bookstores many years ago because I found that unless I bothered to travel to central London to go to the big Waterstone, most of the smaller bookshops didn't really sell what I wanted to read (I have no interest in the bestsellers and their clones widely available everywhere). At least online I can find what I *want* to read rather than the limited selection that the publishers say I *should* read because everybody else does
Edit: that doesn't mean I always buy the same authors - I've always had a fairly wide range of reading. Buying in-store is what seriously restrict reading selections, but I do love going to second-hand bookshops though
