Security
Does no one ever use them to reconcile with bank/credit card statements?
That's the only reason we keep them, then unless needed for warranty purposes are shredded once a month.
And if you DON'T reconcile your bank/credit card statements, you have a naive trust in other people.
It doesn't happen often but we have found mistakes in both types of statement, not to mention small amounts charged to the credit card without authorisation. Small amounts may not matter to me personally, but if it's done by a single perpetrator against >100s people, it's a nice little earner for them.
