If you are wanting to buy something, now is the time to do it. 90% of China's manufacturing is shut down. If items are not being produced, nothing is being shipped, then it is only logical that supplies for certain products in other countries will dry up too.
If you want to order, go to somewhere local that will have it. A lot of people don't realise how much manufacturing has halted in China. Soft industry products aren't going to be restocked for the foreseeable future. If you need something, I would buy it now.
I'm talking about cheap Chinese chit like basketballs, electronics or toasters and jugs. If Apple has stopped manufacturing products, then I can assure you that other companies probably have as well.
I'll be definitely buying a few things to keep in reserve. Even if the economy goes back to normal, I'd need them anyway so it's not a loss to me. But it's better to have some items in stock just in case.
Given that a lot of our meat is shipped over there for processing because it's cheaper to ship it there and back, you should consider what you're eating too.
