expired stock

i went to Shoprite on the afternoon of the 29th September and purchased Illovo Toffee Sauce for ice cream. on returning home and wanting to use the bought sauce on my ice cream i realised that the best before date on the bottle is 07/08/2015.<br> <br> This is totally unacceptable. Why are supermarkets stocking old stock on their shelves and not just old stock, stock that expired nearly two months ago.
