Tesco and Morrisons are both free. (It may be worth diverting to one of them and stocking up). I am using a tin every weekend for a massive slow cooker stew (at least 8 generous portions, although it is a case of hunting for the meat amongst the veg though lol). It is one of our cheapest meals for the week and so satisfying.
Sorry to go off the point, but I just thought I would share!!!
