Do not use this company to publish anything you write unless not making money is in your business plan. They will promise you just about anything for your money. I was smart enough to record all my conversations with the sales person (Grace) and her promises were not honored.
I was was told I had a grace period for refund of all money, I was dumb enough to give them nearly $8000 and i requested a refund a week later because I found out the company is running a scam. They will tell you that you can charge anything for your books and they would only take $3 for printing. The example she gave me was: if I sell a book for $15, I would make $12 and Xlibris would make $3.
They told me I would get 100% royalties but if you look at the contract you get about 25% and Xlibris get 75%.
PLEASE do research before using this company, they will give you sales pitch after sales pitch, like they are owned by Random House Publishing or they publish very well known authors but they will not tell you who those authors are.
