Is buying ink cartridge cheaper than the HP Instant Ink Plan
the HP Instant Ink Plan claims a 50% discount on ink. Plans start at $2.99/mo, 50pages/mo. The XL cartridge costs $36.99 and specs say it's good for 2300 pages. To get 2300 pages with the instant ink plan that would cost (2300/50 x 2.99 = $137.54 over a 46 month period). Am I missing something? Even the $9.99/mo plan 300 pages/mo would still be more expensive; 2300/300 x 9.99 = $76.67 for 2300 pages printed over ~7.5 months)
