Instant Ink program

[BethCh]

 I formerly subscribed to the HP Instant Ink Program. But each month it bugged the dickens out of me to pay $3.50 for a service I rarely used, printing less than 50 pages a month. Therefore I cancelled the program. I have 2 new Instant Ink cartridges that I cannot use because I no longer am a member of this "club." Would it be more beneficial to bite the bullet and pay $3.50/monthly so that I can use these 2 new cartridges, or just buy HP Ink from an office supply store? 

Thank you in advance for the help.

dump the cartridges and printer. the heads clog up, cartridges develop faults not worth the hassle imo. Get any problems despite being a subscriber and qualify for replacdement cartridges which are at fault you get nothing a sthey use device out of warranty bs despite covered for replacement carts when an instant ink subscriber if the carts are faulty. Robbing bunch of ******

By Canon or Epson, instant ink is a rip off
