Almost everyone I know has started recycling their inkjet cartridges and their laser toner cartridges. We have a recycling program at work, and everyone in my family is on board, too. Not only is it better for the environment, but it saves me money on printer operating costs.
There are websites that offer recycling and refills and local stores, too, including all the Walgreen’s stores. Sometimes I use www.inkjetdeals.info because the cost savings is significant and the web site has coupons that you can use to save even more, often for free shipping or an additional percentage off my purchase. It all adds up!
