The world has gone a liitle cray cray !!!!!!!!!, page-48

Nobody is buying 2 years worth of toilet paper.
If manufacturer's produce 100,000 per day on regular basis and 50% of the people start buying extra weeks supply = shelves will be emptied.
The toilet paper supply chain is just too fine tunned to handle spike in demand (there is no stockpiles in supply chain)

The same thing is happening with food manufacturing, cans, office supplies, car parts, you name it it's running out.
You just can't see it in an obvious way as toilet paper. As these items have irregular demand or long lead delivery time for ingredients/parts.
Suppliers/manufacturers have reserve for weeks/months in distribution chain stockpiles.
For example: the aluminum foil is made in China and so is plastic. They are turned into potato chip packaging and yoghurt cup and seal. They take 2 months to go from order to manufacture to sea freight delivery to Australia.
So companies will have packaging for a month or 2 to last between delivery plus some extra for unforseen circumstances.
The shipments from China of such products are disrupted as China's capacity to produce is impacted. The supply chain is drawing reserves.
But come April/May various companies will be unable to package and distribute things like yoghurt and potato chips. Or have spare parts for machinery and equipment, tonner for printer.
And then you'll start seeing the same thing as toilet paper. Dwindling stock > self preservation buying.
(If China doesn't regain full manufacturing capacity)
