That figure, thrown in without anything to back it up, seems truly insane.  I&#x27;m British, but have an ongoing battle with keeping stuff I don&#x27;t really need (and buying in bulk too), and I&#x27;m pretty sure even including all of my fianceé&#x27;s possessions we wouldn&#x27;t come anywhere close to 300k items.  I&#x27;m pretty sure the vast majority of American homes don&#x27;t contain anything like that number of items, unless you count each individual piece of pasta and grain of rice as a thing.
