Ingram Spark ... I was told about this site a couple of weeks ago and I'm really considering it as an option for my book printing and distrubution needs. I like that the cost of submitting a book to their network is only $49 and that includes the print and ebook edition if submitted at the same time and that I can still buy books in bulk at a reasonable price. Plus, once the book is submitted it becomes available for purchase to their 39,000 global retailers for $12 a year access. I think it's a good option. Has anyone used them before?
