Shopping with O’Reilly gives me a nice feeling. I hadn’t bought anything from them for a year so they offered me 40% off my next purchase. Just in general I like their attitude. No DRM on their ebooks – and they’re available in multiple formats. And who could forget the cute animals they have on the front of their books? The only dislike is their exorbitant shipping costs to AU. Ironically, if I ever want an O’Reilly dead tree version I’ll order it from Amazon.
