I was considering submitting to them, but am now having concerns. Can anyone who's published with them in the last year give me some feedback?
It all depends on what you expect out of the experience, I suppose. My book was published this past September, so I haven't had the opportunity that some may have had.
Publicity is mostly up to you as the author, as with most publishers who utilize POD. Champagne does seek out, from what I can tell, some mass publicity events (mostly online) which the author can attend and promote their work. They may do some promotion behind the scenes, but I'm not aware of it.
Pricing is decent, and what I would consider reasonable.
They edit their books, and have tremendous cover artists, from what I've seen.
Distribution has been rather hit and miss from what I've seen. Some titles seem to get stocked in bookstores, and others don't. I don't know if there's a reason for this, or if it's a matter of local bookstore manager preference.
So, as I mentioned, it really is all about what you're expecting out of the experience. I personally don't mind doing most of my own publicity, but feel I would have a little more success if the distribution was more steady.
I've had a fun time myself, though...ymmv.
