Search Amazon for much cheaper prices.
Link(s)?
To clarify from my own search:
http://www.amazon.com/Generic-Remanufactured-Cartridge-Replacement-CH563WN/dp/B0057MBNLG/ref=sr_1_7?ie=UTF8&qid=1465048313&sr=8-7&keywords=61+hp+ink
Looks like some one’s selling pretty much the same as the 61 cartridges shown for $13.
