Bests & Worsts Reviews from Amazon

This is a good story, which I enjoyed. The poor rating is because my overall experience was bad. The story is $0.99 US, but that rises to $2.36 CDN. I wasn't willing to spend that much on a short story, but I decided I would for a novella. I looked at the product description, which put the file size at 399KB with a print length of 72 pages. That seemed to be a novella. However, only 30% of the content was the story for which I paid. The rest was a preview of "First Grave on the Right". A preview is essentially a marketing tool for the publisher that shouldn't increase the price, and it should be made clear how much of the content is previews. I realize most of this is in the control of the publisher, not Amazon or the author, but anyone else buying this story should be aware that they are paying for a 22 (approx.) page story, not a 72 page novella. I would also like to see the table of contents available before purchase so that one could check for previews, etc.
