Cost of ink

I figured out that ink for my printer costs over $11000 a gallon, the little cartridges are $13 each.  I decided to try continuous ink system with the ink costing 3 cent a ml instead of $3 per ml. The jars just sit along side of the printer and is filled there, the ink is sucked into the print heads through the little pipes.

This is the ink jars, you can see the pipes that go around to the front.

This is a photo of the ink cartridges that the pipes connect to, see how they run under the snaps that hold the ink cartridge in place, the cartridges are made the same as the originals but are clear and have the hoses hocked into them.  
        From $3 a ml to 3 cents a ml, boy I love to save money....canyoudougit????
