How often do you buy paper for your printer?
I used to trade in an empty ink cartridge at Office Max for a free ream of paper. There was only one problem. The paper would jam in my printer. I started buying paper.
Then I discovered that Harris Teeter sold printer paper that was really nice. They put it on sale 2/1 some weeks. That's when I stock up on printer paper.
Harris Teeter's printer paper is less expensive than the printer paper sold at Rite-Aid.
I still recycle empty ink cartridges. I send them to PetSmart's Pet Charities and they help to support homeless animals. I like the fact that my empty cartridges are not going to a landfill plus they are helping stray animals.
Oh & if you take in empty cartridges to Staples you get instore $$$ plus the cartridges help reading programs. In my book recycling cartridges at either Staples or through PetSmart is a good thing.
