"Sold out." "Out of Stock." "Maximum of Two Per Customer." If you have recently been to a drug store, supermarket or big box store, chances are you noticed the empty shelves that once housed basic personal hygiene and household products like hand sanitizer, antibacterial hand soap and disinfectant wipes. You may have even seen signs imposing quantity limits on these products in an often feeble attempt to discourage customers from hoarding. Almost overnight, basic over-the-counter products we took for granted became hot commodities.
