I sent some feedback to one of the merchants after buying some of his stuff that said, "Look, nice, but you didn't complete the job." He responded almost immediately with an apology and made up for it with a revision to the product and a supplemental d/l for me and anyone else who bought the product. On the basis of that, seems to me that if you have a problem with something, you still write the feedback and let the merchant know. As for approvals... well, folks, that's advertising.
