Yup, food-wise that's what I've been doing. A good meal in these sort of times doesn't have to be a fancy meal. The greater concern for me are the non-food essentials -- stuff such as toilet rolls, shower products, washing up liquid, detergents, etc., which are becoming increasingly hard to get.Buy staple ingredients. Panicked buyers tend to buy stupid things and they leave a lot of the useful stuff behind.
Hopefully once some countries get over the worst, they can begin reaching out to others to provide relief.
If it weren't for the small spare supply I built up, I would have nothing today.
