Brought up by someone at our writers group meeting. He was really sold on their "distribution." Which seems to me is a term that includes "listing" as opposed to actual presence. It's also an offer to do a lot of things with each one costing an additional amount. Red flag to me was the absence of any % of "royalty" on POD sales, and no mention of the cost to an author to buy their own books. I also couldn't figure out exactly how you were supposed to submit your book -- other than in some electronic form. Given some of the strange ways I've seen people "format" that could be interesting. They also offer to scan a document, but I doubt that includes correcting for scanning errors --- bet you have to pay for someone to do that.
Other thoughts, anyone?
