I researched 100 ink cartridges and, at almost $10,000 per litre, this very popular HP cartridge is the most expensive in the world
For only $19.99, you can replace the HP 65 Tri-Colour ink cartridge and continue printing. But here’s the catch: that $19.99 only provides 2ml of ink, just enough ink to print around 100 pages.
