Food

The other day I probably had the worst fruit salad of my life. I think that is the difference between supermarkets like Tesco, where I got the food and say... Marks and Spencer, where I can't afford the food (and I make decent money). On the one hand this is evidence that there is a direct correlation between cost and taste. On the other, why are places like PoundSaver, PoundStretcher and other bargain, about-to-expire supermarkets so delicious?
