Because people are idiotsMy Mrs, like many others, had a bit of an obsession about buying them during covid. I think she had around 100 packs at one point. Thankfully they have been used over the years and have a more sensible amount now.
I really don't understand why everyone went mad for them, then. All the main supermarkets sold out and I had to get some from a smaller local shop. (we were not living together then)
