I was delighted to find that you can enter two codes on Dixons' website to purchase the Samsung NC10 black.
First enter NC10BLACK that should reduce the price from £311 to £299 then enter the discount code SALE25 to get the 2.5% reduction which leaves you with £292.49 free delivery.
For people who use quidco and its equivalents you could get it even cheaper. This is the cheapest price around currently as far as I'm aware and I have just ordered it for myself after a week or so of searching for the best price.
But hurry because the NC10Black code expires on Sunday.
