For my inkjet printer, use for copies and color, I just get the cart's refilled at Costco. Just started using their service. So far, great. No issues.

By refilling used carts, you don't have any carts to get rid of.
For black and white. I use laser printers. Toner carts, last forever. Get
4-5 thousand pages per toner. (depends on amount of print per page).
