Anytime Iāve gotten a physical copy of one of their books, it hasnāt been directly from them but has been via Amazon UK (with no delivery charges here if the order is over a certain amount).
E-books directly from them are good value though (especially with the 40% discount) and, unlike Amazon, you get their e-books come in several formats (epub, mobi and pdf) so not locked into one propietary format like Kindleās (plus there arenāt any DRM Digital Rights Management protections on the files so they can be easily transferred and converted to other readers).
