If you have a Staples near you, you can get $3 in Staples Rewards for every ink/toner cartridge (up to 10 a month) you turn in. They used to limit the brands, but now you can bring in any, whether its name brand or generic. You bring it in, give them your Rewards number (or phone number, if you misplaced your card), and they send you a coupon a month or two later for the amount you're due in rewards. Its good for a couple months, and its only valid at Staples. However, they have a lot of good rebate offers (like packages of photo paper for $1 or $2 after rebate) so you can turn the ink rewards into cash this way.
