How does one acquire Epson made ink in bulk, outside of cartridges?
To clarify I am draining OEM ink from larger OEM carts.
I probably have 20 to 30 350 and 700 ml carts purchased over the last several years all from .05 to .10 per ml.
Even if you purchased new K3 OEM in 700 ml carts it is around .32 per ml or half the cost of the P800 ink which sells for around .65 per ml. (P800 is a different ink HDX I believe, it is available too.)
It is a full time job keeping all these carts full for all these printers but we have cut our ink costs by almost 75%. Tons of good usable ink out there at really low prices from broken and dying printers.
To add all of the larger carts 150, 350 and 700ml have anywhere from 15 to 30ml of ink in them when they stop printing. We draw all of that remaining ink out and use it up. Everyone else just throws them away.
