Case in point: I luckily found some hand gel still for sale online. Probably the very last one around here. So I stocked up - not resale quantities (thought it would have been trivial) but definitely more than I needed - something like 10 pieces. Why? Because the price was low and I'm doubtful I'll get to see any more this year.
If the price had been even slightly elastic, I wouldn't have bought 10 pcs for $10 each. I would have probably spent about the same, and gotten 2 or 3. Even better, I would probably still be able to get it from the groceries store, without any shortage - and buy just one as needed.
So we have two scenario: if the prices stay the same some people stock up early, and most are left without. If the prices go up proportionally, we end up spending a trivial amount more (let's be honest, spending an extra $7 on hand gel is not a tragedy) but we have no supply problems. First because there is much less stocking up, and then because everybody is incentivised to produce and sell more.
