I was just about to post the same question, because I had the same experience. I thought I'd been featured, now I have a sad.
I logged in just now, and scrolled through the recent sales, clicked on one I liked, and saw the link on it
It sucks if that link is just to take a visitor away from our stuff, sending them to the homepage. If that's the case, FAA should add a dialog box when someone clicks the "buy" button asking "Are you sure you want to buy this image?" And again "Are you really really sure? Look through our collections first!"
Edit: and now the link is gone from the top of the page.
