Western Creek Australian Chedder Cheese - 35p per 100g at the deli counter
Cheaper than all the BOGOF deals around and very tasty!
BOGOF usually works out at about 45p per 100g.
Being from the Deli the shelf life is not as long, but i bought some in Exeter, full promo tickets, on Sat pre-cut and shrink wrapped with a "Best Before" date of 31st Jan.
Cheapest cheese for ages...
