How can I save money on ink with my HP Officejet Pro 6830?

You can save up to 50% on ink by signing up for HP Instant Ink service at hpinstantink.com. The savings claim is based on the HP Instant Ink Service plan price for 12 months compared to the cost per page of the majority of color inkjet printers under $399 USD. You can also get one month free if you sign up within 7 days of purchasing the printer by entering the code FREEINK at checkout. (Page 2)
