That outfit doesn't look very professional to me. Their words to imply that your books will be sold in bookstores are the same ones that fee-based POD's use to imply the same without actually saying that the books will be there on the shelves. They plaster the page with Google Ads like a content-based website - commercial websites normally make money by promoting their own business, not others. And there's that phrase that always sets off my alarm bells, "Publish your book free." At the best, they sound quite unprofessional.
Also, there are a number of media and communications companies with "Mondiale" in their names -- for instance, Mondiale Publishing Ltd. Picking a name that's only one terminal vowel removed from that is either sneaky or gormless.
This subject has come up recently on another forum. So I did some checking. It looks like they don't have a single book in their catalogue that is less than 100 years old. All a bunch of reprints of public domain stuff. I checked with Ingram's automated number on the sales of one of their books. I picked Balzac's Ursula. They sold 21 books last year, 29 so far this year. 6 are on order and none are in stock. Making the sales of this book a whopping 56 POD books. I checked a couple of their other ISBN numbers - for instance that classic Venus in Furs. That ISBN isn't even valid in the system. Nor were the three or four others I checked.
After a while, I did find a contemporary book for sale on their site... Say What?: Highlights from the Glory Days of the First George W. Bush Administration by Diane Stingley - Sales this year - TWO books... Sales last year - THREE books. Total requests now - ZERO ... Total on hand - ZERO... Wow - there is one happy author!! She sold FIVE books! And 3 of the ones sold are for sale used!
These guys are doing some major spamming of forums right now - especially ones with kid authors. The big key word is publish your book FREE. Kids love FREE. Sounds like a no-go to me too. XOX - Montana ...
