Back in August, we told you about InvisibleHand, a Firefox add-on which spends most of its time hidden but pops up if it discovers that you're looking at a product you can get cheaper somewhere else.

Commenters on our post loved it, and now you can try out the latest version of the add-on before anyone else. The company behind InvisibleHand has offered 200 Pocket-lint readers access to the new version, which adds Google search integration, a "more refined" notifications experience and support for German retailers.

 You can grab it right now by being one of the first 200 readers to head over to and use the code: "invisiblePL" without quote marks. When you've downloaded it, head on back here and let us know what you think in the comments section.
