Last time I needed ink for my printer I went to ebay and bought a set of 4 50g bottles of ink and 4 hypodermics to suck up the ink and squirt it into the ink cartridges without removing the cartridges from the printer.
The whole lot cost 10 euros; I had it sent to a parcel shop in Germany because the delivery cost to Switzerland was too high.
The supplier was http://www.ebay.ch/itm/121603730469?...%3AMEBIDX%3AIT
I have no connection with this supplier but for 10 euros what can you lose?
Original cartridges cost over CHF 100,00
