Basically, she just refilled her existing cartridge with a syringe and some black ink! "The bottle and syringe we bought on Amazon as a kit and it comes with 500 ml of black ink. Our printer, which is a Canon, only requires 18 ml of black ink per cartridge," user @jennacarlesimo said.
She added, "So think about that. That big bottle of black ink, for $22, comes with 500 ml. Typically, we are spending $25.99 per ink cartridge — that's just for ONE! If we can get 27 uses per bottle from Amazon, that can save us up to $700!"
After a quick Amazon search, I found several kits just like the one they explained in the video. The one below is 500 mL and costs $22.99.
And I even found a smaller one that is only $11.20!
What a truly genius idea! Hooray for saving money!
