There is no easy answer when it comes to Publish on Lulu worth it or not. It really depends on each specific case and book. For some people, Lulu may be the best option and for others, it might not be worth it.
Here are some things to consider when making your decision:
-Are you trying to get your book into bookstores? If yes, then Lulu is not for you as bookstores typically do not buy books from Lulu.
-Are you trying to get your book into the hands of reviewers or other influencers? If yes, then Lulu might not be the best option as it can be difficult to get your book noticed on Lulu.
-Are you trying to make money from your book? If yes, then Lulu might not be the best option as you will have to pay to have your book printed and there are also other printing options that might be better suited for making a profit (such as CreateSpace or IngramSpark).
-Are you trying to have complete control over the design and layout of your book? If yes, then Lulu might be a good option for you.
-Are you trying to have a print copy of your book for yourself or for family and friends? If yes, then Lulu could be a good option for you.
Overall, there is no easy answer as to whether or not Lulu is worth it. It really depends on your specific book and what your goals are for your book. If you have any questions, you can always contact Lulu customer support and they will be happy to help you make the best decision for your book.
