Dyson DC40 Animal for £198 at Argos. Possible 1.1% Quidco too.
Best price I've seen at the moment. Personally I think it's a lot better to get the Animal model as opposed to the Multi Floor because it comes with the Tangle Free Turbine Tool which costs about £39.99 on its own from Currys or John Lewis.
The Dyson DC40 Animal is currently retailing on both John Lewis and Very for £349.99.
