Interesting new feature on Trademe (New Zealand's version of e-bay)

New Zealand's online auction site Trademe has an interesting new feature. When you enter in the title of what you are selling it brings up a message "Similar items have sold with a start price of between $x.xx and $x.xx"

I thought that was pretty cool, it also adds to the new feature they introduced a couple of months ago where it automatically predicts what category your item should go in when you start typing the title.
