Is there a big difference between Lulu and Createspace? I do see they are both free.
I am not up-to-date on CreateSpace. When I went into self-publish I decided that Lulu was better for me, easier to use and their payment system was better -- i.e. they paid me monthly in GBP via PayPal rather than a USD cheque.
Your requirements might be different. Anyone considering these services should thoroughly read the T&Cs - especially about getting their earnings out. Some sites have high minimum earning levels before payment is made. If you don't have a US bank account then a USD paper cheque can cost more to process than its worth.
I looked up your books by Lulu and the one published earlier this year by Lulu is only available as a Nook.
I don't know if you're talking about my books; but all my three self-published* books are available as paperbacks from Amazon. PINOTAGE is also available as a Kindle and in ePub format at Barnes & Noble and the Apple iPad store.
*I also have a traditionally published book
The latest one from November is available on Amazon, but isn't even sales ranked after nearly 2 months.
If that is the TWSz book -- that has only appeared on Amazon this week. It takes some time to go through the process of getting the ISBN on the databases and arranging printing rights with Amazon.
As you can tell from the title it is a very niche subject - hence the high price - however I have been happy with sales via the Lulu site which have come about because of a post I made on a forum a LinkedIn.com
I have also published, using Lulu, books by others, some are here

This all looks very vanity to me. Maybe I'll look a little closer at Lulu if it's recommended.
Self-publishing is being used to differentiate from traditional vanity publishing which charges authours many hundreds or thousands of dollars/pounds up front. With Lulu you can produce and get just copy of a book for the cost of one paperback.
Please do check out Lulu and CreateSpace and come back here and tell us what you found and what you are going to do.
