Somebody’s had enough, as explained in ars technica.

A Boston man has filed a class-action lawsuit accusing hardware maker HP and office supply retailer Staples of colluding to inflate the price of printer ink cartridges in violation of federal antitrust law. According to the suit, HP allegedly paid Staples $100 million to refrain from selling inexpensive third-party ink cartridges, although the suit doesn’t make it clear how plaintiff Ranjit Bedi arrived at that figure.

Good luck, Ranjit. We’re all for lower overhead.
