You could stock up today if you're concerned about a steep price increase for "foreign" products. For me that would be coffee and olive oil.

It depends on how much space you have in your home. I tend to buy textile products in bulk when they're on sale. When stuff disappeared during COVID, I had a 6=18 mega roll package of toilet paper that lasted a couple / few months. I ran out just as the Mexican toilet paper arrived in the stores.

Really, I buy a lot of any non-perishable staple when it's on sale.

But imagine if Avian Flu (or anything) becomes a pandemic during our fun little trade war.
