I found these bargains in two of the small Sainsburys Local stores yesterday (St John's Road Tunbridge Wells and Crowborough) although a third, much larger local did not have the reductions (Crawley Queensway). It seems the reductions were in the stores that bump the prices up for the honour of being local IYSWIM.
All these products were marked as being SALE items and in both stores, most were close together in the same section.
Sainsburys organic spaghetti in sauce (tin) 13p
Sainsburys tinned chili con carne 35p (was 1.38)
Dynamite chili con carne 41p (was 1.65)
Ovaltine original 46p
Hundreds and thousands 24p
Askey's cornets 24p
Merxchant gourmet jar sun dried tomatoes £1.38 (half price)
Sainsburys basics kidney beans 10p
Heinz macaroni cheese 55p
Heinz pot snack - chicken and vegetable curry 36p
BGTY Tuna fusilli (tin) 38p
BGTY shell bolognaise 38p
Also Baxters and Heinz soups were half price and Heinz tinned spaghetti and curry beans were 75% off
The list above is just off my receipts - there were a lot more ranges reduced.
Nothing was short dated - closest was Oct 09 for the ice cream cones
