I planned

I bought items 2 weeks ago if I had the option to freeze them. The only thing I didn't plan on was supermarkets not having stock of what I needed, along with my back locking up last weekend meaning i couldnt go out for several days. Its still agony but had to brave shops today to get the bits i couldnt get on Friday.
I don't think it's necessarily about lack of planning. It's a combination of people going mad and getting as much food as possible thus not leaving enough stock, shops then not stocking shelves quick enough for demand, people who might be working/have children to look after and that's their only chance, people waiting for pay day so they can get their food shop, people waiting for shops to make further reductions because they're trying to keep costs low/might not earn much or the odd few who forgot something because no one's perfect
