:0) Its common sense really, lack of goods, late goods ( fresh foods) profit loss. I went into Sainsburys on Friday, they had rows of empty freezers, very basic goods peas, frozen chips. Some may say well my Sainsburys was full, well all that depends on how far the goods have to travel to you local shop. All in all Sainsburys is one business and the profit margin affects every store and price, full or part empty.
