With the price of butter and margarine shooting up this really is a good deal.
Tesco have Utterly Butterly on BOGOF at £1.80 for two, but you can use a coupon to get a further 30p off making it 75p for each 500g tub. Much cheaper than the Tescos own brand "Buttery" spread.

Top tip: Fool your friends into thinking you use expensive butter by simply using margarine and ripping holes in the bread.
