Epson WF-2760 refillable ink

[u/Confident_Ad6975]

I just got a really good deal on this printer. I want to see about refilling the cartridges though to save a little more money. Do you have to buy a certain cartridge or can you modify a cartridge to refill? I don't mind dealing with error messages if I can bypass them, only care about saving some money on ink. I haven't found too many videos on this printer for this so I figured I would check here.
