REDfrog inks are inexpensive compared to the big box stores.  We utilize a local company that remanufactures cartridges with great precision.  Their extensive testing process produces a superior cartridge and is recognized as an industry leader in both inkjet quality and customer service.  Their “Green” process reuses the cartridge not by refilling it, but by taking the cartridge down to the core and rebuilding it.  This process reuses the plastic case instead of putting it in a land fill.  Why pay for plastic every time and then throw it away?  It is less expensive to produce, cheaper to buy and saves the environment.
