I recently started using the scanner for my shopping. unfortunately this system is not well thought out. at the beginning of the shopping trip there are the racks with fruit and vegetables, then bread, yoghurt, meat etc. and at the end the heavy items such as washing powder and drinks. you can't pack them sensibly this way because all the perishable goods are crushed by the end of the shopping trip because they are at the bottom of the shopping bag. so you have to put all the goods on the scales first and then pack them at the end of the shopping trip so that nothing is damaged. Everything clear?
