At the Dell outlet store they have the above for £136.92, using the £55 off voucher with free delivery. They also had a few for £129 odd with 512Mb RAM and 4GB SSD, but I would say the above is better value for money.
They had quite a few in stock at the time of posting.
Dont forget to add the £55 off voucher to make this worthwhile.
