Butchers all the way if possible. Buy 3 kilo of mince get one free and at a good price and good meat. Chunk of top side for about 12 quid for the family tends be the same price if not a tad cheaper than tesco and so much better. Some chunks of beef shin nice and cheap for casseroles or ox tail for slow cooking.
Only thing our butcher is pricey on is chickens so get them from aldi
