When I search for cheap carabiner's on Amazon I notice that my former purchase no longer shows up on amazon search, even though it is prime, and offers great price+product characteristics: https://www.amazon.com/gp/product/B016CMFESW https://www.amazon.com/gp/product/B016CMFESW This pattern seems to be showing up more and more. Maybe it's just that the FBA marketplace is flooded with too many choices, but my "best" often seems to be not searchable any more. In the carabiner example I present, there are plenty of tiny carabiners or those with weird shapes, or expensive ones. Just not low cost, non-tiny, normal shaped carabiners
