True, but we've seen the recent appearance of "generic inks" and now "refill stations" where existing ink cartridges can be re-filled at a pharmacy (e.g. "Walgreens" in the USA) for half the cost of new ones.
Is this also true with pigment inks?
If I had been present at the creation, I would have given some useful hints for the better arrangement of the Universe.
