Staples coupons - $20 off $100 and 5% given to a charity of your choice

School supply time is fast approaching, and office supply time never seems to end. But through 7/29/09, you can save on both and donate to a favorite charity at the same time when you buy from Staples! The following codes will each take $20 off a delivery order of $100 or more, but each donates 5% of the order total to a different cause, so make note of the one you'd like to support: 54835 for Ashoka, 72382 for the Boys & Girls Clubs of America, 89750 for Earth Force, or 64335 for the Hispanic Heritage Foundation.
