* Stock most items overnight so that if you absolutely need something you can prioritize getting there before they open and likely getting it rather than having to come back over and over (or go to multiple other stores), which limits exposure.
* Set aside additional hours before the general opening for seniors.
* Limit high-demand items. This does have some perverse ramifications for a few items. For instance, we wanted about 4 dozen eggs to get us through a few weeks. Unfortunately the smaller packs were limited to 1 so we ended up having to buy 5 dozen.
* Flood the market with in-demand items to create confidence. I think this is a Seattle thing, but last week I started seeing social mediate posts showing literal aisles composed of nothing but toilet paper. Many people (myself included to some extent) are just just buying because they don't want to get caught without TP when they run out, but if they feel that it's likely it will be in stock they won't rush out to buy some immediately.
