Am I the only person that buys sensible amounts of things?

I don't buy one bottle of detergent. I buy 5. When there's two left or whatever, I have weeks to get another 5. If the item has high shelf life and I know that I need it for essentially forever, I might even get 10 or 15 or more.

And no, my home isn't especially cluttered.

Boggles my mind. Why is pasta even sold in 500g bags?
