Lexmark has launched an online rewards program which gives consumers rewards for returning used inkjet cartridges.

When customers buy five ink cartridges from Lexmarkstore.com within a 12-month period, they get one ink cartridge free. After they return five empty Lexmark ink cartridges to Lexmark within a 12-month period, they can get a second ink cartridge free. This program applies to almost all Lexmark branded inkjet cartridges.

Cartridges returned to Lexmark are recycled through its cartridge collection program.
