Changing retail distribution to Lulu marketplace distribution
I started two projects on Lulu, one for the paperback version and one for the hardcover version of the same book. I uploaded all the necessary files and once I got to the pricing page I realized retail channel pricing is very high and I can't make a profit at all. What I want to do is change the settings of the books to Sell on Lulu marketplace and get my book on Amazon via Kindle and Createspace.
So I went to the Title section of the books because that's where you choose whether you want the book to be sold on Lulu alone or whether you want retail distribution. These options are however not visible to me now, just the title and author name.
Then I tried to delete the projects and start fresh but Lulu says if the projects are deleted the ISBNs will not be availble to be used on new projects. I purchased these ISBNs separately.
My questions are: Is it possible to change the distribution type without deleting the projects? and since I bought these ISBNs can't I use them in new projects? Or is this rule only for the free ISBNs given by Lulu?
Thanks in advance for any insights and sorry about the length
