Yea, looking at these listings again, you can also see that the photos for each one of the auctions are duplicates of the other. Which is fine, I suppose, for fungible items that have no appreciable variation in appearance. But I'm not sure that applies to these kind of razors.
Also, it looks like the reserve price for the DT#13 is $75. Still I agree with others here -- the whole setup makes me wonder what's going on.
