I managed to get 6x600ml of double cream on New Years Day years Day for 13p each, and 2x600ml of whipping cream for 23p each last Sunday.
I wasn't sure if it would work with whipping cream, but it did, so I was chuffed.
We now have about 2kg of butter in the freezer
The other 500g or so has gone, some went onto the scones made with the buttermilk, which went nicely with the 8p tub of clotted cream we got too.
We know the best times to go to Tesco for the markdowns here and have got some real bargains lately
