Save Up to 50% on Ink: Savings claim is based on HP Instant Ink Service plan price for 12 months using all pages in plan without purchase of additional pages compared to the cost per page ("CPP") of the majority of color inkjet printers < $399 USD, market share reported by IDC Q3 2013. CPP comparisons for standard capacity inkjet supplies are based on estimated street price and page yield as reported by Gap Intelligence MFP Weekly and IJP Weekly Reports Q3 2013. Actual savings may vary depending on number of pages actually printed per month and content of pages printed. Never run out of ink: Based on plan usage (without excess printing), Internet connection to an eligible HP printer, valid credit/debit card, email address, and delivery service in your geographic area. Internet connectivity is sold separately. Rollover pages: Rollover allows unused pages in a month to be placed in a rollover account and then applied to pages in excess of your monthly allowance. The rollover account balance is limited to a maximum of your monthly service plan pages (e.g: $2.99 plan 50 pages = 50 page rollover maximum). Change or cancel plans online anytime: Cancellations and plan downgrades are effective after the last day of the current billing cycle. Plan upgrades are effective during the current or next billing cycle. See terms for full details.
