For those who buys cookbooks on their kindles or ipads. Amazon is having a kindle sale atm, and it includes some interesting cookbooks link.
I got Dan Lepard's short and sweet which I have lusted after for a while for £3.99. The hummingbird bakery cake day is also £3.99. (I'm trying hard not to buy it). I also see Mary Berry's winter book, and MasterChef's cookery course.
