One thing is clear: the mark up on products must be huge and the confidence to seduce consumers into buying more than what they went in for enormous if it's possible to have LIDL, NETTO, Sainsburys, ASDA so close together. And these are just the supermarkets clustered in that corner; if we extend the area by less than 2 miles we could add Morrisons, ALDI, TESCO as well as smaller stores (2 ICELANDs for example).
