Delia's new Christmas cookbook, order now from Tesco online for just £12.50, plus get free delivery and 250 Bonus Clubcard Points.
The link should take you to the books homepage - better to go through Quidco or similar for cashback. On the Tesco homepage you can see the deal advertised. They also seem to be doing a free delivery promotion (not only for orders over £15, as it says somewhere on their website).
Website said they were due to be delivered within 28 days, but I got an email a day after ordering saying the book has been despatched. Also, I don't know how long the offer is valid for.
