Review: Five Stars - good did work for job
Review: 7kg and post free would be a very good bargain. - I received the goods in very quick time. however the description is misleading. Its states '1 Carton Containing 10 X 2.27Kg / 5 Lb Blocks'. I only received one 5lb block and not 10. This to be fair was what I was expecting reading between the lines, as £16 for a package weighing in at 22.7kg and post free would be a very good bargain.
