See the "review" here (preserved for posterity in the image below).
And here is a screen shot of the half.com listing (link here, but this may not be active for long).
Note the seller, eric_k1979 -- the same account from which Harriet was caught selling free books from publishers last year.
This is a clear violation of Amazon's terms of service for the Vine program.
