I think the cheapness is actually part of the reason certain things end up being targeted. You can spend a $100 on frozen meals at a supermarket and have 10 of them. They're a lot more practical for a 2 week quarantine but you're not going to make a dent in supermarket supply unless you're spending 1000's. So these things aren't targeted by hoarders. If you spent $100 on toilet paper however you've just wiped out a big chunk of the shelf stock. Others then see that the shelf is almost empty and you get a chain reaction.
