Yeah - Aldi's pink lady apples, clementines and maris piper potatoes are disgusting compared the exact same ones at Tesco 
God knows what they do to their chickens, steak and pork chops because they also taste exactly the same as Tescos - weird!!
Their frozen veg - oh my God.
Seriously - they do really nice frozen burgers with stilton, some very nice wines and a good Irish Whiskey too. There is plenty of tesco own brand stuff that I think is sucky and every week I am tempted to complain about how quickly Tescos produce/milk goes off or the bread gets mouldy but am too lazy never get around to it
