Because of the higher cost of PoD, I'd have to lower my margins significantly in order to offer the book at a reasonable price.
That's a shame. Thanks for explaining. ;-)
Of course! In any case, if you are interested in the physical book, drop me a line, I’m sure I can work something out for you :)
Cezar, I suggest you print on demand on Amazon (KDP), it’s much cheaper than Lulu and you can certainly make a profit.
That is a great suggestion, actually! I'll look into it!
