I was talking to a chicken farmer the other day he said he had just bought a tonne of wheat for £158 if you call it 150 it works out at £3 for 20kgs pus the cost of bagging it up why are all bags now 20kgs anyway supposed to be health and safety law but other things are sold in 25s I noticed price dropped when the weight did but soon went back up to the price for the bigger bag I think theres a lot of mickey takers have a look on internet for prices then challenge your supplier I did
