I built something cool for a client a couple of years ago. When sorting on price (or title, or anything), it shows you the price range (or title..) in that page ($100 - $350) on mouse hover in a tooltip. Surprisingly it's not something I've ever seen anywhere else.

This way you can instantly jump to the price range you are interested in.

I think no one does this because SQL syntax just gives you COUNT and LIMIT primitives so those become the terms that developers think in.
