Where to buy Z-680's in the UK?

[Technoed]

OK, a couple of weeks ago I ordered the Logitech Z-680 speakers on Amazon.co.uk. When I placed my order it said that they'd be dispatched within 1-2 weeks. But today I received an e-mail saying that there's been a delay and that it would now be another 1 to 2 weeks before they're dispatched.

Me being such an impatient individual, I decided to look on Kelkoo as well as my usual online stores to see if anybody else had them in stock. No such luck. Every online UK retailer I checked didn't have them in stock.

So, what I want to know is, does anybody on here know where I can get the Z-680's and have them delivered to me by the end of the week?

Thanks in advance.
