Hello–I am thrilled to see your new digital book about Tokyo. At the same time, I am surprised to see that the 3 formats (pub, kindle, pdf) are separate and that it would cost $45 to get them. It is common practice, like SmashingMagazine, to offer the 3 formats when you buy the rights to read the book. $15 is already expensive for a digital book, and if on top I must choose the format that will take me through time, I will just not buy any of them. So sad. I was looking forward to it. I hope you change your policy.
Thanks for your query and apologies for the slow reply. Actually we’re new to digital publishing, so we’ll investigate your suggestion and research common industry practices etc. Cheers!
