I spent £125 on non-perishable stuff yesterday, all stored under the bed, nothing will be wasted as it's stuff we would have usually anyway, so will get used up over time when this thing blows over. It's almost just like shifting the spend forward. I also have a chest freezer and stocked that up a bit, we are a family of 4 and I reckon we could go easily 3 months now, provided the water supply doesn't stop, which I can't see happening as a result of this anyway. I think under normal circumstances just from having things in the house we generally have maybe a months worth of food in the house. If you really had to you can live on rice and beans and multivitamins for a long time.
