Well I don't know specificly about your regular corner shop, but when I go to the butchers its much cheaper than the supermarket and far better quality. When I go to the fruit and veg shop its much cheaper than Tesco and much fresher products. There is no doubt that supermarkets can be cheap with lossleading products, its just whether people shop around for those products or buy everything else while they're there and get stung by the hidden higher prices.
