Have you signed up for Office Depot Worklife Rewards yet? There are lot of great perks including $2 per recycled toner/ink cartridge (up to ten per month), exclusive coupons, rewards certificates and more. I traded in some used cartridges in store and received a $62 certificate in the mail and a coupon for $10/$10 in the copy/print service area and $10/$50. My plan is to buy 2 more cartridges and get the free shredder and use the $10 to get some mommy cards. Also, Office Depot has another recycling program that earns you gift cards when you send in (at their expense) used electronics and media. They also offer a free computer scan and business seminars in their web cafe.
