I bought BGS's $149 package. Unfortunately, it produced minimal results--3 sales (at the reduced price required by BGS), incl. 1 sales after a direct mailing program at the last moment. And, to preempt the (what looks like a standard BGS's) response that some books simply don't sell, mine has been selling through other direct mailing (and cheaper) services, as well as for free, through word-of-mouth on GRs. I was just hoping that BGS would be more efficient and multifaceted, and less effort from me would be required. I was wrong. I have to give credit to BGS team: they do respond, albeit not always with very helpful advice, esp. on FB. All in all, not a worthwhile investment for me.
