ebay.co.uk and ebay.de are running tests on a new search interface at the moment. It would appear that they're trying to make it so annoying to search for anything that you give up and go out and buy a new one at the shops instead...
Luckilly if you scroll down to the bottom of the page there's a tiny hard to see link which allows you to opt out of the test and go back to "find stuff easilly" mode.
I really hope that they don't introduce this rubbish. (although I am a complete luddite - just look at my watch

)
