I bought it just for that purpose its Royal SC800 paper shredder and it does a fantastic job. I have 3 or 4 or maybe 6 restorations going on as you read this and a couple not quite stock renovations to a /5 & /6 and one I'm not quite sure about so I have a lot of receipts to store. Its amazing how compact that SC800 makes them!!!
DISCLAIMER: I do not work for or have any connections to the Royal company, I do it for fun and to maintain a negative balance in my bank accounts.
I wouldn't be having fun if I wasn't spending money on my BMW's.
