Just filled the Saxo at Sainsburys, £1.319 per litre no limit on sales. No queue either. Did notice that there is a limit to how many cans you can fill. Plastic must not be larger than 10 litres metal no bigger than 20 litres Maximum quantity is 30 litres in any combination of can. I presume this is not just Sainsbury but the law to prevent unfortunate disasters with loose petrol in accidents. So how come there was a photo at weekend of a guy filling 5 or 6 plastic cans?
