I'm not doing it, I wont be doing it. We did our weekly shop yesterday, just bought the usual.
The shops will only run out if people behave like headless chickens. Thankfully the supply system is pretty robust and once the clowns have bought 30 bottles of handwash they wont need replacements so the shelves will fill again.
Handwash and toilet rolls are both produced in the UK, the two items people are losing it over, so we are not reliant on imports for those. Lead times should be short, no need to panic.
