Saw this when I was flicking, looking for one for ages - it isn't a bad deal but only if you find the accessories of use - the machine can be had from around £159 from elsewhere online (and nearly £170 from amazon.co.uk) however it doesn't come with what is included in this pack.
If you find the additional items of use then it is far cheaper to purchase them as a bundle.
Oh and the other good thing that swayed it is that you can pay with some form of Payment system they call 'flexipay' so you pay in four instalments.
Don't forget quidco also :)
