It would be really helpful if Lulu responded to e mails. I have sent three e mails regarding a problem with my order and have yet only received the standard response that they will reply in 2 to 4 working days. They haven't. I recommend another self publishing company to my colleagues as they respond within 24 hours - A nice response, Lulu to date have not responded to any, thought I would try Lulu as they are cheaper, maybe because of this.
This is my first experience and saying I am disappointed is an understatement.
