can anyone tell me if the shopping book is right (the 2010 one) as it says that mr porky pork crackles are only half a point for a 20gm bag now that sounds sooo good but on the back of the packet it has 125 cal and 3.2sat fat?? didnt know wether it was a mistake or cos it was natural it was lower! im hoping the books right but seems too good to be true!
