I didn't mean to imply any large sum of monies, but something significant enough to warrant their time. The bulk of the monies does, indeed, go to the publishers. I know from experience in the printing industry that printing itself is expensive. Probably 50% of the publisher's take goes to printing, the rest divided between advertising and profits. For a typical 200 page math book going for say $80, it is probably something like $40 to the publisher, $5 for the distributor, $25 for the reseller, and $10 for the author(s). (Numbers VERY hypothetical). Of the $40, the book probably costs between $20 - $25 in materials and printing costs. Most of that in the paper and binding costs. For the reseller, it is broken up into more advertising and stocking costs (and of course profits all along the way). I don't think anywhere on that route that anyone is truly GOUGING the end user, but there certainly is a lot of padded profits all along the way (typically 30-50% on most durable goods - don't know what it is for books specifically though).
