This is how we keep ink costs low at LATITUDE so Chicago artists can keep working and stop worrying! We use "empty" Epson cartridges and Inkjetmall's refillable units. This is good for the environment, good for artists, and good for our organization! If you are an artist with empty ink cartridges, consider donating them to LATITUDE instead of throwing them out. Through us, the Chicago photo community will make good use of them.
