It takes up a little bit of room, but buying a shredder is a smart use of your money and space. You've heard the horror stories about identities stolen because of careless disposal of things like credit card offers and bank account statements. A shredder can help you avoid trouble, protect yourself, and keep your table junk-mail-free.
I like to destroy the necessary envelopes as I go through the mail to prevent clutter and save time. You can purchase a shredder from any office supply store and they run as low as $50. Is shredding part of your routine?
