One of the big costs of ink-jet printing at home is the ink.
A quick visit to google shows that there are plenty of companies out there willing to sell ink cartridges and refills for the major printer brands. Many of these are way cheaper.
Also, some local companies (like costco) will refill empties.
Are any of these a good deal/value?
Ages ago, I tried refilling myself with mixed success. Besides the ink on my fingers, I believe that the heads ended up clogged.
