Don't know what to do with your used ink cartridges? You can check my Resources for Decluttering page for some ideas, or you can read this post by Tech Savvy Mama.
I read it literally minutes after I had changed out my printer's cartridge and had made a note to go to Staples for more.
Although come to think of it, I don't think they gave me a coupon when I turned it in. Nor do I think they took any money off of my ink purchase. I'll have to check my receipt. But at least I don't think they chucked it in the garbage, as I would have.
Cut me some slack, people. Quinn was taking up most of my attention during this purchase.
Anyway, there are lots of ways to recycle ink, if you're not a moron like me. Look into 'em.
(This doesn't actually count as an item because it is a consumable.)
