Query: Unfortunately overpriced by publisher

I am often disappointed to find that I am not able to justify buying a novel I have very much enjoyed, like Anne Perry's mysteries, for my Kindle due to the unreasonably high prices that the publishers seem to want to inflict on the buying public. Perhaps they wish to discourage readers from using e-books, since the cost of the novels are sometimes even higher for the e-books than for the same material in a paperback. I have a library of close to a thousand books, mostly in paperback, which I eventually want to convert to the e-book versions, but I am not able to do this due to the costs. The publishers will need to get on the electronic media train, because it will, in time, either carry them into the future or run them down and crush them.
