You can now buy recycled printer cartridges that are 100% guaranteed from Castle Ink. They have ink refill kits, inkjet cartridges, laser toner cartridges for a huge variety of printers (Dell, HP, Epson, Lexmark, Brother, and so on). AND they are cheaper than new cartridges. Even more impressive is that they PAY up to $4 for your old cartridges. So, why are we buying new cartridges and toner??
