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.
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.
And before you're forced to join the Sickness Cult as the condition of being allowed to buy them. Not just at the store, either.
What if – and these what ifs are no longer extreme scenarios – it becomes a Bidenite "mandate" that in order to buy – even online – you must produce evidence of The Jab having been received? Pope Fauci XVII has already been so intimating and in a week or so the Jehovah's Witness of Sickness will no longer be constrained to merely intimate. It is expected that, once anointed, the new Defender of the Faith, Joe Biden, will decree the universal wearing of the Holy Rag and it is likely he will follow up with a requirement for a more permanent induction into the Sickness Cult via the ministrations of the Holy Jab.
This will not be enforced by law, probably. Religious movements don't need laws when they have the power of excommunication.
Apostates and heretics will simply be cast out. Excluded from life, shunned. The Holy will turn their backs on them – and close their doors to them.
