It’s a good idea to stock up on parts for your cars and any other machinery and appliances you might have and ammo, too. From Eric Peters at ericpetersautos.com;
Some people are stocking up on ammunition, which is never a bad idea as ammo retains its value better than gold or silver and – unlike gold and silver- is actually useful in and of itself.
Another item of similar usefulness to consider stocking up on is service/replacement parts for your car, which may become hard-to-get in the weeks and months and (god help us) years ahead as well as more expensive to get.
And not just in terms of money.
Things like engine oil and filters, tune-up parts (e.g., spark plugs, spare spark plug wires, coils, distributor caps, brake pads) and the other items that need to be periodically replaced to keep the wheels turning. You may want to have them stocked up before they are no longer stocked…
