In particular, searches for computer equipment is generally frustrating. I've also seen sorts result in a large number of irrelevant outdated used items getting filtered to the top.[1]
I'm willing to cut them slack since it's good enough, but look at Newegg to see how it should be done. It's not a completely fair comparison (since Newegg specializes in this), but they do it so much better.[2]
