There's no "too late" (coming from someone who's in Madrid, Spain, which in terms of the pandemic might as well be the future).
The reality is that one or two weeks from now at most most idiots will have toilet paper for months and you'll be able to buy normally again.
Goods considered non essential, however, might be scarce since those shops will close as the workers are told to stay home. For example, I'm doing a lot of studying and I'm out of sheets of paper. Office supplies stores are closed, and buying that on Amazon feels like overkill and a little socially irresponsible, so I have to make do without them.
Check your house for random silly stuff you might miss if you're stuck at home.
When I go to the supermarkets the missing things are snack foods, beer, ice cream, etc. People have a lot of time to kill and those items arent replenished as much since they're considered non essential.
One of the nice things around here is stores like Walmart that sell groceries (so they are considered essential) also sells everything else (such as office paper).
Out of curiosity, I just checked and amusingly, depending on your local store, you can get it through their grocery pick-up service too. Probably also delivery, but I don't live in an area where they do that.
That's what they've done in Bavaria. They apparently missed some shelves at the discounter I was at yesterday, and the cashier reluctantly told me that he couldn't sell me that pack of contact lenses I'd picked up in the health and beauty aisle (contact lenses are usually available on the shelf in Germany). He thought I might be able to get them at a pharmacist.
keep in mind that a store is just a frontend for several supply chains. The workers making the product might stop, the transporters might as well, and even the workers that refill the shelves might stop refilling non essential goods.
Our crockpot cord broke, just a normal power cord that a standard computer monitor would use. However, amazon is quoting April 21st for a basics replacement while bestbuy said they probably would have it for pickup tomorrow but then delayed...so no crockpot food until I can get a dumb cord that comes with every computer monitor.
