First deal I am posting after being through this site for long !!!
Just found this on dell website. Looks like a good configuration for £549 to me. However does not include Bluetooth for which you have to pay £35 (approx) extra.
New 5% voucher makes this £521.56 - MikeT
Dont forget Quidco 5%.
Last night the website was saying this price was available till 29th July and today says 12th August.
A little bit of haggling with Dell Salesline may also work, however you would miss quidco
