I've been creating paper editions of my books, revising as I go along, for myself. Sales are not the point, since the books are free downloads on SOL and the other usual places, albeit without the latest revisions yet, and I've been putting up PDF versions of the paper editions as well on Google Drive.
I've ordered at least a dozen books over the last few months, not a huge investment given the size of the books and Lulu's ongoing promotions and sales, but I am impressed with their simple but effective packaging---the volume has a slightly padded wrapping, and in turn is shrink-wrapped to a piece of cardboard inside a correctly-sized flat cardboard container, which itself has a strap around it.
There is no effing tape!
Cover colors have been generally accurate, even if today my copy of Goddess arrived with a very slightly greenish Hebe on the cover. Perhaps she was carsick from the road trip. Others, including Chloe with very warmish tones on the cover, have arrived spot-on.
Interior layouts are fine. Like Ernest, I give them exact print-ready PDFs to work from, so no automated conversion.
Overall, probably 4 out of 5 stars to Lulu.
