What he said.
With such a large number of people who self-publish I think it is up to the buyer to do their research. I would never buy anything written by an author who was unknown to me without doing a bit of binging around. I also consider who published the book. I won't even consider buying a self-published book without reading a (free) chapter. The last thing, and least important to me, would be reviews.
As far as 'No Refunds, No Exceptions' I believe this is a universal policy with ebook retailers. The only possible exception would be if something was linked incorrectly and the wrong file was downloaded.
