A Snarkling commented that Booklocker.com seemed to be a straightforward company that publishes using POD.
I ankled over for a quick look at the website.
It's clear they aren't trying to rip you off. There are no banner headlines about "be published now". She's got a list of reasons you shouldn't submit a manuscript, which makes me think she's a pretty savvy marketer. She says she makes her money on sales, not services. That's a good thing.
She's got her head on straight about discounts, and most important PRICE POINT for books.
If you're going to go POD, Booklocker.com looks like a reputable candidate.
But also notice, on the submission guidelines, she's rejecting for spelling, hate, and religion. No mention of "is it any good". And that's the nub. She's not going to rip you off, but there's a limited review process going on. That means, if you offer it up to me as a publishing credential, I'm not going to take it at face value.
This is the place for hobbyists. Snark Central is a place for people intent on making some serious dough on their work. One is not better than the other, they serve different needs.
