If incubation is taking on average 5 days, I'm thinking do buy more than normal such that one may have a couple of weeks worth of groceries, in order to, if need be, effectively isolate...but, in my case, that would mean going without sliced bread - the best thing since...

Either way, provided people are not buying foods that will go off, after a while the shelves may go back to normal with such change in shopping habits/frequency, yes?
