One of my wife's coworkers used her lunch break yesterday to panic buy toilet paper at the Sam's Club next door. If anything, there may be a glut of toilet paper as most is produced domestically or exported.
Perishable foods, like bananas and pineapples, are most likely to disappear from store shelves in the coming weeks if the strike drags on. Impacted consumer goods are probably a mix-match depending on port of origin.
