I think that the old http://bookscan.us
have a better deal?
I mean, is $ 1.00 / Book AND "Up to first 300 pages treated as 1 book (BE). After first 301 pages, every 200 page increment will be treated as one additional book count. Page count includes only main body of text. Front and back matter (preface, index, acknowledgement, index) will be scanned as our courtesy."
